Aprs balloon tracker

Launch a hacked Canon camera to the stratosphere and photograph the blackness of space. At the time, the standard recovery method utilized a cellphone programmed to communicate its position after landing. Unfortunately, once you let your balloon go, you had no idea where it was until it came back to the ground and phoned home. What we wanted was a way to get live reports from our flying machine while it was in flight. The solution is the Automatic Packet Reporting System.

APRS is an amateur radio communications system designed to report the location, altitude, speed, and other information about the sender. This combination of key components along with some other standard gear is a tried and true platform for a cost effective journey into the stratosphere. Within about 2 hours our balloon would climb to 94, feet, attain ground speeds of over mph, and record hundreds of stunning photos along with dozens of videos.

All the while telling us exactly where it was and what was going on. APRS is an amateur radio protocol designed to report the location of a sending station on the move. This system has been adapted to many uses, including the reporting of telemetry required to track a balloon like this. The fantastic thing about APRS is once you broadcast the packets, everything else is done. Thanks to ham radio operators around the world, when you broadcast a packet, there are receiving stations listening for them nearly anywhere you might be.

The receiving station forwards your packet to internet sites which provide near real-time reports of your flight, including location, altitude, speed, and any other data you can fit into an APRS packet. Utilizing a radio capable of tuning the APRS frequency, it is also possible to directly receive the packets from your balloon even with an inexpensive receiver. This is important after landing, because there is a good chance that no stations will be close enough to hear your packets once the balloon is back on earth.

Chances are the final packet that reaches aprs. It is a sonic representation of your packet. All you need is a radio receiver that can tune to the broadcast frequency of your Trackuino If your APRSdroid happens to be running on a smartphone with 3G or 4G access, it can also be used to map your location versus the location of your balloon.

The APRS amateur radio network passes along digital data packets sent by your transmitter, so you can track its location. This is an Arduino shield that combines a low-power radio transmitter with a GPS receiver and some other components to provide everything needed to track our balloon via APRS, including GPS location, altitude, speed, internal temperature, external temperature, and battery state.

The Trackuino can also drive a beeper or buzzer, to help you find which tree it is stuck in during the recovery phase of your adventure. The heart of the Trackuino is its milliwatt radio transmitter made by Radiometrix. The Trackuino is not available anywhere as a pre-built component, or even as a kit.

You must have the circuit board made and then solder in the components by hand.They are available in portable, car, and high altitude balloon versions, and are available pre-configured with your amateur radio callsign.

Hide welcome on start-up. Imperial units. Horizontal speed in hours.This web page is a quick throw-together of the images and experiences. This one was assembled for a water landing high probability in our area by placing it in a lightweight water bottle.

The black plastic bag on the left serves as a"streamer" to slow its descent. The team prepared the simsat for launch on 24 July using a small WXX balloon.

The Space Camp team had planned on a launch-and-forget approach to the smaller expendible cricket sats. These simulated satellites consisted of a matchbox size transmitter think key-chain FOB transmitter and 9v battery. The only telemetry was temperature. But from temperature and thermal gradient knowledge, one can infer altitude.

No direction finding was planned, so no DF gear was on hand. After the days launch activities were over and several small simsats were launched, we thought it would be fun to go see if we could find one. We chose to go look for the one called Cricketsat G2, since it appeared to only have a 45 minute flight life before it was heard to descend. This suggested that it was not that far away.

To a ham radio enthusiast Direction Finding is a cause for a challenge. We wanted to go see if we could find one anyway, with nothing but our hand held walkie-talkie. We used what the Hams call, the fade-circle technique. This is a cimple technique for just this kind of as-you-are recovery effort.

The Process is simple: All you need is your mobile rig and an HT and some greay matter between the ears, and you can find anything. Almost as easy as driving right to it and back and forth a bit. Just visualize signal strength, and always go to the middle of your maximum signal along any line of travel. Then turn 90 degrees and again go to the middle of the signal maximum, turn 90 degrees again, and repeat, and repeat.

As signal gets stronger, switch to HT. As signal gets stronger, switch to paper clip antenna and repeat. As signal gets stronger, remove antenna completely and repeat. Finally, reach out an pick up the transmitter. The images below chronicle my approach at finding this payload. The relative signal strength is shown by colored dots as I drove and then walked to find the balloon.

It was placed on the map only after we had found the general area of the landing. This object was uset to mark our location we got out of the car to start our foot search. This symbol allerted launch control where we were beginning our foot search. The above image shows our initial drive from launch site with our mobile radio along track line north of the launch site.

We had no idea where the balloon was or how far! The next image shows our first weak detections along the highway: Next shows a plot of my first perpendicular driving leg after going north and then turning south by car The next shows the second Perpendicular leg by car no more roads : This next slide shows the first HT results and confusing circling in the farmers backyard clearing while we tried to visualize how the signals were arriving: And here is the final image of the assault on the corn field!

Anyone can, and you don't need any DF equipment. Just your mobile, your HT, and a signal to find! Just depends on how much gas you have in the tank, and how far you are willing to walk once you get to HT range. This final picture shows what the Cricket sat looked like when found.

I could not even see it until I was one corn row away! Also shown is a closeup of the postcard that was attached to this Cricketsat. This payload went to overfeet 20 miles and came down about 35 miles north of the launch site. The winds showed a significant change in direction at altitude as shown in the APRS track below.APRS is a popular method of geo-tracking over amateur radio.

We have outdoor-safe versions, modules and cables to connect these to radios and computers. Transmitter Hunting Products Transmitter Hunting, or Foxhunting, is a popular way to combine outdoor activity with the amateur radio hobby. MicroFox Transmitters The MicroFox line of hidden transmitters are small, self contained 2-meter transmitters designed for walking foxhunts. It is programmable and remote controllable via DTMF tones, and great for longer range hunts.

It conects to an HT's SMA connector and an antenna, and by tuning to an image frequency, the signal strength can be adjusted to bring it to a useable level. It includes a VHF transceiver and password controlled access to seven digital output lines.This is often bulky and power hungry. 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.

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. Getting your amateur radio license is a very easy and rewarding process. Getting your license allows you to broadcast on frequencies allocated solely to amateur radio.
