The next year a small contingent of Americans attended the European Championships, held at the same field in Bulgaria that would later host the WSMC. Looking forward to flying the S5 event in Bulgaria the next year, Matt and I decided then and there that the concept of radio tracking merited further investigation. In particular, a transmitter intended for dragonfly monitoring seemed to be especially appropriate for our purposes.

We ended up purchasing three of the ATS tracking transmitters from the company, and they were kind enough to loan us a receiver for the duration of the Championships. The ATS system as well as similar systems from Walston and others consists of three primary components:. The specific trackers we used were the A model of glue on Avian transmitters. Here is the link to the product information page for that series. The transmitters are all built to order and they do want a good lead time.

The transmitter shipped in a clear plastic tube taped to a magnet.

The magnet held open the contacts of a reed switch. No other action is needed. When the battery is exhausted after a typical day lifetime, the transmitter is discarded. Larger beacon products such as the Walston use replaceable batteries, but are typically much heavier.

In practice, we found the range of an airborne ATS unit to be in excess of a mile, while the range on the ground was much more limited, generally several hundred yards at best.

The operator will typically wear headphones to hear the signals collected by the receiver. The two bearings should, ideally, intersect on the location of the rocket.

Our first experience using the trackers in the heat of competition was on S3 day. Kevin maxed in all three rounds, with one of his models lost and the second returned using the ATS tracker. Two days later we used the system for the S5 event.

Jim Filler had a great flight, but visual tracking was lost as the model approached the ground. Here are the steps that Kevin Johnson used to operate the beacon system on his S3A parachute duration models.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

Dec 19, GPS tracking has been rare in the past, but recently there have been more offerings, lowering prices and increasing functionality.

This page goes over the background of GPS tracking and provides lists of what's required to get started. See the References section at the bottom for links to background information and additional systems. If figuring this all out seems too complex, you can skip down to my Selection Flowchart.

Only the simplest, Technician class, is needed no Morse Codebut it's still an investment of time. I got mine a while ago and suggest that it's worth doing because it opens up more options even if you never plan to use a HAM radio to chat.

See the ARRL page for the background and requirements. Basically, you take a short written exam that you can study for online. The Real Flight transmits on Mhz and does not, nor does the B. For extreme altitude flights, Beeline makes two units that transmit at MHz 2m and also require a license. For more information on frequency and relative range, see Ken Biba's section Relative Tracking Range section at the bottom. The GPS unit itself flies in your rocket and transmits position to the ground.

It has three basic pieces: the electronics board, a transmitter antenna and a battery. On the Big Red Bee, the battery is integrated. Above are the three transmitters considered here. The transmitter needs to be integrated into your rocket, either in the avionics bay or in a separate bay. In order for the transmitter to broadcast to the ground station, the airframe must not be made of metallic or partially conductive substances carbon fiber or aluminum.

The worst antenna location is between and in-line with threaded rod and near flight computers. The nose is often wasted space in a rocket, so it makes sense to take advantage of it.

See my Plastic Nose Mods video with techniques for installing a bay in a plastic nose cone. The GPS unit is flying in your rocket and transmitting information.Using the template and measurements from her site, along with some paper, paper clips, and tape, you and your kids can create a fleet of spinning, colorful helicopters.

The kids can even practice their science and math skills by experimenting on the measurements to test how far or fast the helicopters fly. Instead of using hard-to-find parts to build a catapult, you and your kids can put one together quickly with craft sticks, rubber bands, hot glue and a bottle cap to hold the projectile.

Place pom-poms, marshmallows, or even LEGO minifigs in the cap, and let them fly! Not every contraption has to be fancy or even very complicated to be fun. With just five components found around the house, kids can turn a plastic bottle into a rocket in almost no time at all.

Older kids might even like to tackle the project on their own, experimenting with ways to make the pack more stable when worn and adding their own flair to a fantastic craft. Over at Frogs, Snails and Puppy Dog TailsJaime tackled a classic contraption, the marshmallow shooter, and wanted to find ways to make it both fun and toddler friendly.

The secret ingredient? A pool noodle. You might have to help with the hot glue, but while you craft it together you can chat about airflow and friction. Over on the phenomenal family blog All For the BoysAllison Waken provides an easy tutorial for creating a unique airplane that flies even better than just a plain old paper plane. Kids can spend hours coloring and decorating the detailed designs, then creating and launching their one-of-a-kind rockets.

Have you had hours of fun with a Stomp Rocket? Make your own! Older kids who are looking for a little more of a challenge, will particularly like this DIY shuttle launcher from Under the Sycamore. Once the shuttle and launcher are put together, kids of any age will adore stomping on the launcher and sending the shuttle into the sky.

The best contraptions are the ones that your kids invent on their own, so give them a box of ideas and let their imaginations fly. Your kids can build anything they can dream up, from a working contraption to a one-of-a-kind piece of art. Sign up for your weekly dose of parent fuel and Puget Sound family adventures.

TeleMetrum: GPS Tracking for High Power Rockets

Categories Alex Hunter Posts: I have learned so much by reading these forums I figured that it is time for me to contribute. So many people have questions about GPS, so I hope this will be of assistance. I have attached pictures of the GPS rocket locator that I built a few months ago for my first basic stamp project. The locator displays the current coordinates and can also store the last minute of data.

This is useful for when the rocket lands and the radio connection is lost, but the last data points received can be viewed and plugged into my Garmin extrex.

Two components of the system fly in the rocket: the GPS receiver and the radio transmitter. This transmitter sends the serial data from the GPS to a receiver on the ground which is connected to the BS2. The three pushbuttons below the display are used to control the recoding function and to view the saved data. I used two aerocomm AC www. These radios have a range of up to 4 miles line of sight and are meant for transmitting serial data.

Also, they are small and lightweight, and cost much less that comparable radios. Configuring them was a bit of a challenge.

I ended using the stamp to send the TTL level serial programming strings to the radios. I chose this because it was the cheapest and smallest I could find, but now I wish I had bought a WAAS capable receiver for the greater accuracy.

I have attached the BS2 program.

Bottle rockets are great projects for you to make, or to give your students to make. The materials are also pretty easy to find, which makes it a great fit for day off from school or fun in the summer. But, figuring out exactly what to do can be hard, and it can be hard to know where to start. This article will teach you two different ways to make a bottle rocket that is definitely going to be a success.

To build a bottle rocket, start by rolling a piece of paper into a cone and covering the outside of it with duct tape. Then, attach the cone to the bottom of an empty plastic bottle and cut out 4 cardboard triangles to make your rocket's fins. Attach the cardboard to the bottle and then fill up the bottle with water. Once you've done that, poke a hole in a cork and plug the opening of the bottle with it.

Finally, attach a bicycle pump valve to the cork. To learn how to launch your bottle rocket, scroll down! Did this summary help you? Yes No. Log in Facebook Loading Google Loading Civic Loading No account yet?

Things You'll Need.There are two main types of radio tracking. These are GPS based and direction finding. In each of these categories there is equipment that requires an Amateur Ham Radio license, and other equipment which does not. I will try to present an overview of these types of equipment and the associated methods. GPS based systems have the advantage of telling you where your rocket is, with good precision. It provides a specific position to go towards and can be used with mapping software to plot an approach path.

There are some very good apps, that are free or inexpensive, to track GPS coordinates on smart phones. There are apps available, and simple interfaces, to allow receiving APRS data and plotting on maps using smartphones and similar devices, such as tablets and even iPods. Amateur Radio systems allow for more flexibility in settings and frequencies.

They are available on different bands, and if built up from components can even have multi-band capability in the same unit. Non-licensed bands are limited in power and transmitting antenna. Very useful for high power rockets.

They may not have the range for very high altitude or long range flights. Some non-licensed systems have Bluetooth interfaces that can send position data directly to a smart phone, but others require the user to read the coordinates from the receiver and manually enter them into a GPS device. The advantage to GPS based systems is the search is much simpler, since your rocket essentially tells you where it is. There is also the possibility, depending on specific systems, to have telemetry data for things like system voltage, temperature, etc.

Some units will take analog or digital data points, and send them as telemetry data also; so you could set up a barometric pressure sensor, accelerometers, even switches to detect parachute deployment. There are trackers made specifically for rocketry. Among the most popular are the units made by Big Red Bee. They are available for both the 2 meter and 70 centimeter ham bands.

They can be ordered with default settings including the callsign of the purchaser, so only the receiving station need to be configured. You can also purchase a programming cable to allow various parameters to be customized, such as how often it transmits position data, whether the signal should be digi-peated, a short text message, etc. These trackers provide a very simple option for a beginner, with the possibility of more control over configuration as the need arises.

The second option, assembling your own tracker from modules, allows a wider range of choices of band and frequency, GPS type, and APRS module capabilities. Assembling your own system provides the most flexibility, but also means that you have to do all configuration and integration yourself. You can select a more standard GPS, or one capable of high altitude operation. This is not usually a significant limitation, but if you are flying a rocket above that level you would need a specialized GPS.

Note that this is a GPS receiver module only—no display, bells, or whistles. APRS tracker modules vary in capabilities; such as types of telemetry, ability to decode APRS packet, and even the ability to work as a digi-peater. You may be able to find kits for a bit less. Transmitters or transceivers can either be simple modules or complete hand-held units.

Byonics and Argent Data sell modules of varying capability. Many hams prefer to use an inexpensive hand-held. These are generally capable of operating on more than one band, and can be used on a number of frequencies within each band.
