3. Upgradeable firmware Altis Flight Manager software for OS Windows only with Telemetry Converter 2 Introduction The Aerob Tec Altis GPS is a telemetry and recording device with integrated GPS receiver and barometric altimeter It is designed especially to record the altitude and the coordinates of the R C aircraft during its flight with telemetry support The unit has very small dimensions and a low weight The Altis GPS calculates trajectory coordinates of the aircraft It also senses barometric pressure variations caused by altitude changes of the aircraft These data are stored in the internal memory of the device 3 How does it work The Altis GPS uses a GPS receiver with a built in antenna Unit is able to get a fix in less than 35 seconds in the case of cold or warm start In the case of hot start the required time reduces to less than 1 second The location accuracy of the unit is smaller than 2 5m and the speed accuracy is lower than 0 1 m s These values are reported for open space In order to improve the resolution of altitude and vario measurements Altis GPS is also equipped with fast modern digital pressure sensor This sensor enables to sense very small pressure differences This gives the unit an altitude resolution below 0 5m with sample rates as low as 0 1s Since the atmospheric pressure changes over time these changes will affect your Aerob Tec Altis GPS User Manual OO cAerobTec measurements For t
