The growing range of telesondes of Komoline all are served by a relatively small number of highly configurable software defined receivers. The receivers are so flexible that all standard and customized telesondes of Komoline can be used with the same receivers. The receive frequencies supported by the receivers are 400MHz to 1000MHz, with a 1Hz resolution and 0.1ppm accuracy. ASK,FSK,GFSK,MSK,PSK are all supported with configurable modulation index, baud rate and other transmission parameters. Configuring the receivers for a given telesonde is as simple as selecting the model from a drop-down menu in the software or, for customized models, reading the configuration file for the same.
The receivers are actually double-receivers with dual antenna-diversity, a monopole for low angles of elevation and a quadrifilar helix for zenith view. The switchover arbitration is built-into the system and is transparent to the user. Armed with a two-level forward-error correction decoding matching the telesondes and and RS485 based long-cable drive capability, the receivers can connect to a PC or laptop virtually anywhere in the vicinity and provide real-time data.
Physically the receivers are small, light and very easy to install. Tripod installation is virtually a ten-minute job. They can be installed permanently or on demand for a balloon flight.
