Telemetry equipment complex

Telemetry equipment complex (TMEC) is designed to transmit on-board information from a high-dynamic facility to ground receiving points (GRP).

The onboard telemetry equipment (TME) includes: a GNSS receiver with an antenna, a telemetric information transmitter (TIT), antenna transmitter kit and embedded software.

GRP a set of antennas for work in the near and far zone, a GNSS receiver with an antenna, a TIT receiver, turntables, a GSM/GPRS modem, a PC with software, an autonomous power supply device and a tent (awning).
