Aprs weather balloon tracker

We no longer manufacture our own APRS transmitter. We recommend purchasing the StratoTrack instead. It is extremely easy to integrate into any weather balloon system and operates without the need for a separate flight computer. Click here for more details.

Track your weather balloon payload with live data anywhere in North America! You don't even need any special equipment on the ground. You will be able to track your weather balloon on Google Maps with any device connected to the internet, including smart phones and tablets!

At just under 25 grams it requires less than one cubic foot of helium to compensate for the extra weight. Just plug it into our Eagle Flight Computer and suspend it below your payload from the included 24 inch data cable and you are ready to track. No need to hassle with creating your own antenna setup, dealing with a coaxial cable, or setting up an extra power supply.

Balloon Path Settings:

The Radio Bug has a mW transmitter mounted in the center of a dipole antenna. This is the most effective antenna for tracking weather balloon payloads over long distances. Studying for the test takes only a few hours. You set your callsign by editing a file which the Eagle Flight Computer downloads onto the micro SD card when it is powered on. This packet of information will include position, altitude, speed, temperature, and pressure. The APRS network operates at a single frequency. It would be like trying to understand a hundred people all shouting a different message at you at the same time.

As a common courtesy to other uses on the network, we limit the transmit interval to once every minute. Theoretically it is possible that you and someone else could transmit at the same time preventing your packets from being received and decoded by surrounding IGates, but this rarely happens.

A packet takes less than a second to transmit. Above 60, ft, we've seen IGates over miles away from our payload receive our signal.

IGates have a hard time picking up your signal when your transmitter is close to the ground. They almost always require direct line of sight. If your payload is on the ground and a hill separates it from the nearest IGate, your signal will not be picked up.

For this reason you should not rely on our APRS tracker to locate your payload once it lands. Even if the satellite tracker is on the ground, it still has direct line of sight to satellites in orbit as long as it is facing up. This is also why you should never use a Styrofoam cooler as a payload enclosure.

They occasionally roll upside down when they land preventing the satellite tracker from "seeing" satellites in orbit.Pages: [1]. Hello all! This is my first post, and I hope that I am posting into the correct area. I am involved with a weather balloon project in which we are hoping to track our own payload using APRS.

I'm sure my questions will be very elementary, so I apologize in advance. What all is involved, hardware and programming-wise, in tracking our payload using APRS? Will we have to program the Arduino to decode the APRS information, and if so, where can I go to read about the process required? In general, is APRS a standardized data formatting protocol? What will be required for a ground station? Does that involve a TNC? What software will be required to track the payload?

Any and all information will be greatly appreciated. I feel pretty overwhelmed as this project is an extracurricular activity on top of my 20 credit unit semester, so at this point and just being pointed in the correct direction would be a godsend.

Thanks so much in advance! It's ham, not "HAM". The Tinytrack is a "tracker", not a GPS. Typically a tracker has a GPS unit attached so that position data can be encoded, but they can be usefully used without a GPS e.

The OpenTracker line of trackers is open source where the TT line is closed source. I have flown many OTs, and I'd recommend you use them because they're open source, if for no other reason. If all you need to do is track the balloon, you don't need an arduino. For the ground station, you'll need a TNC, a computer with soundmodem type decoding software, or maybe use an arduino to implement a TNC which is a non-trivial project.TXT file seems to have been lost.

This will bring up every digi over a million square miles but at least it will only do it once a minute, and no worse to locals than just another mobile in the area. And beingit will not bring up the WIDE fill-in-digis that may not have dupe suppression. This makes sure that everyone in range of a digi will hear one and only one copy of each packet. The goal is that a digipeated packet is cleared out of the local area in ONE packet time and not N packet times for every N digipeaters that heard the packet.

Notice, this is contrary to other packet systems that might want to guarantee delivery but at the expense of throughput. APRS wants to clear the channel quickly to maximize throughput.


Unfortunately we launched on a day with a totally unexpected and unusal weather pattern bringing in winds that took it North instead of the usual East. After about 17 hours and at night over Lake Ontario it expeirenced severe weather and lost pressure and began to descend as shown in the map below. Landing: After experienceing severe weather, the balloon began leaking helium and descended fortunetely over land.

And our prediction is shown below. Since the payload is solar powered, there is no reason that it should not continue to beacon its position for some time to come unless it landed upside down or in permanent shade.

We invite any hams in the area to go take a listen. It transmits once every 2 minutes on Watch the brief launch video. This was a surprise to see so many APRS balloons on a single day. The scope is not understood. But a visual scan zoomed in on the eclipse path on APRS. FI only found about Their mission was to stream live video of the moving shadown of the moon acorss the Earth. Clearly smart people realized that adding an APRS device would make it easy to recover. If anyone has more info, please fill us in.

Another plot of the same balloons shows on the North Carolina Near Space web page shown above. That page describes two of the above Eclipe balloon missions in detail. Notice, at the time of this screen capture, he balloons out west, having been launched earlier, were achieving higher altitudes than the ones lanched later in the east as evidenced by the blue range circles under each balloon.

The mission ended up being a tether mission, but this package shown at far right was my latest version of my typical balloon tracker using a soda bottle for solar heating and water survival.

Note, this year I put the tapered end of the bottle "down" so that it would sit lower in the water in the event of a water landing and be more stable.

See description document Mission - Solar Heating Data: Midshipmen 1C Bottomley and Daly 3 May Re-Flight: The near image bottle at right was the solar thermal payload that was re-flown to get the intended solar thermal data. The image shows it in comparision to the more conventional approach some take to packaging in foam. The mission proved our thesis sincethat balloon payloads do not need insulation and heavy foam, but simply need clear containers to take advantage of solar heating.

The payload shown here used the conventional foam packaging top but also a solar thermal package as well. The Thermal payload consisted of three concentric layers of clear plastic. The inner layer was a single layer of bubblewrap around the electronics. The second layer was a plastic water bottle and the outer layer was a larger soda bottle. There were thermisters in each of the three layers and one outside as shown here.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

It makes tracking pico balloons, weather balloons, model rockets, RC aircraft, and anything else that flies simple and easy. Important : LightAPRS uses the amateur 2 meter radio band which requires an amateur radio license to operate.

If you have installed it before for a clone Android board, you don't have to install it again. Don't worry, it's really easy. Just download the following driver from sparkfun. Download and install Arduino IDE. If you have already installed Arduino, please check for updates. Its version should be at least v1. If you have any questions or need supoort, please contact support lightaprs. I'm interested in pico balloon flights but I have no experience.

What kind of balloon, solar panel, capacitor, etc. No you don't. Since pico balloons are very small and light, you are FAA exempt. Please check out this page for detailed info.


You can use any type. For airborne projects such as balloons, rockets, rc planes, drones, etc. So just cut a light 50 cm.

I would like to use it as a car tracker is it possible to use an external antenna? Skip to content.

The Arduino program contains all software layers to generate FM AX25 like a classical tracker and transmitter separatly. Indeed, the microcontroller drive the dds to simulate FM modulation and generate Hz and hz signal as predict the ax25 protocol. As you can see, the weather station, used here for measure temperature, can be recharged by a solar cell and thus dispense with external power.

It ends with a classical 2N transistor amplifier delivering a power of 0. Power must be 5 V, the card does not have regulator because it can be powered by four 1. Consumption is reduced to 20mA. It will add a USB serial adapter card to program the microcontroller. The interface that connects to the J2 connector. J9 jumper in position J9 jumper in position when no programmer connected to it to prevent inadvertent Reset. In the programming environment for Arduino, check the operation of the download.

Caution must be a TTL compatible signal 0,5Volts. J3 pinout. Obviously, there is no weather sensors connected to the J3 connector. It is for you to make a software change according to your needs. The principle adopted is virtually identical to the weather program, except that the frame is adapted to transmit telemetry. This little digital transmittermake you many services for APRS experiments at close range. The card is cheap to make and easy to integrate into a classic electric box.

The Arduino software is modified depending on your applications. I installed a mini APRS station in my garden with a 6V solar cell without changing the batteries since 10 months. Est-ce que vous auriez un petit ampli 12 V dans vos cartons?

J'aime J'aime. Till now I have make some change in code, first time tracker send GPS data and after few second send telemetry with weather data.

Do you maybe know what is wrong with frequencys? Or best will be if you have time or maybe any another who have make this, that you help me so that I can change code, so that he work without AD….When you receive a message, you can answer it directly by pressing a button.

In addition to ready-made texts, you can also enter a completely individual text But it was not yet! This is just as easy as sending normal messages to other callsigns. How this works exactly is described in www.

So you can send a link in advance, which you can follow live on the map. Look at the photos! Why the goal to build the smallest APRS transceiver? Well, I love technical challenges! And why still? Quite simply: the part can always be with you! DB1NTO had done a fantastic job!

Next stop, trying to find a good antenna to get the most of the 1W output because this one has to become an emergency device while trailrunning! But should be! No significant losses in RX and TX thanks to high quality low pass filter. About my transceiver was reported on numerous sites. Some of them are below. Thanks for the reporting about my Transceiver! Youtube from Ham Radio 2. The Transceiver is about so small like a matchbox only about 1,8 x 3,3 x 5,6 cm! For example : GPS is cyclically activated in battery mode and deactivated to save battery.

It makes tracking weather balloons, model rockets, RC aircraft, and anything else that flies simple and easy. It is able to report location, altitude, temperature pressure and humidity to the internet or direct to an amateur radio once a minute for up to twelve hours with just 2xAA batteries. Because Tracksoar is open source you can add your own modules to accommodate custom sensors, inputs or outputs to meet your specific requirements.

Tracksoar can also use a range of drop in transmitters to allow for easy world wide operation. By flying Tracksoar on a weather balloon you can reduce the required helium and balloon costs per launch and it can pay for itself with just 2 launches.

No other APRS solution offers this level of integration, compact size, and customization. Additionally all profits from Tracksoar sales go to supporting the Santa Barbara Hackerspace and improving the resources we offer to the community. We at the Santa barbara Hackerspace have been involved in over a dozen weather balloon launches. We have had a lot of fun with these launches and learned a lot, but found some issues with existing means of tracking.

Most of the commercially available APRS trackers are closed source, large, and heavy, all of which add to the cost and complexity of launching a balloon. So we decided to do something about it, and the Tracksoar was born. The Tracksoar uses the amateur 2 meter radio band Tracksoar has been developed for nearly two years now and has been proven on many flights. We have gone through several iterations improving and refining the Tracksoar and continue to develop new features.

The Tracksoar is built around the excellent and mature Trackuino project. We have modified their code and schematics and board a bit to make the Tracksoar as compact, lightweight, power efficient, and integrated as possible. APRS has been used by amateur radio operators for decades to send location and weather data.

With sites like APRS. The Tracksoar also has a boost regulator to allow a range of power options, accepting between 1. The Tracksoar software is built around the open source Trackuino firmware, which is well developed and quite mature. US licenses are good for 10 years before renewal and anyone may hold one except a representative of a foreign government.
