AIM XTRA GPS flight computer

The AIM XTRA is a complete GPS flight tracking computer. Tracks up to 30km (~20 miles) line of sight (with included antennas) with an accuracy of approx 10m (3 feet) using the AIM BASE radio receiver. With a Yagi antenna connected to the AIM BASE, over 100km tracking range is possible!

Packages - fast shipping via EMS

The AIM XTRA 2.0 is a GPS electronic payload, incorporating a RF transmitter and additional sensors for a complete telemetry system.

The AIM XTRA makes use of an advanced Swiss engineered avionics GPS for precision airborne location tracking. GPS co-ordinates are stored onboard flash memory, as well as being transmitted to a ground base station (AIM BASE) which connects via USB to a PC, laptop or even a netbook.

Thats just the beginning... The XTRA includes a pressure sensor capable up to 100k feet. This allows for very accurate altitude readings. The GPS and pressure sensor work together to give vertical accuracy and resolution.

Also included is a 105g linear accelerometer for motor characterisation and flight analysis. An onboard triple axis 16g accelerometer adds resolution and accuracy vertically, while giving you extra latteral acceleration data. An onboard temperature sensor is also inlcluded. A 3 axis gyroscope gives rotation data. Additionally, a 3 axis magnetometer offers magnetic field data.

There are 4 high current (40 amps continious) output channels available which can be configured to fire for any duration using multiple triggers (altitude, apogee, velocity, time).

Each output channel can be used as an input channel to sample an external sensor such as a thermocouple mounted on your motor, or even a pressure transducer located inside your motor.

All this information is relayed in realtime to your PC via the AIM BASE receiver. The AIM XTRA includes a very powerful (50mW) transmitter opperating in the 432-434 MHz band.

Best of all: it's so easy to use! The AIM XTRA is fully USB compatible. It doesn't use translators which emulatate RS232. This really is a fully "Plug and Play" solution.

Purchased the AIM XTRA and looking for information?

Your AIM XTRA includes the ability to have its onboard software (firmware) upgraded by the user from his or her PC. Your altimeter includes the latest firmware available when shipped.

Because software changes can lead to different behaviour, we have to make sure you get the correct manual corrosponding to the firmware loaded onto your device.
We have included everything nescesary for you to get started in a convenient "package".

A list of downloads is availble on the left menu.
