ELTA focuses on the ground segment of Earth observation, navigation and telecommunications markets…


Simulators are high performance devices which generate complex signals or emulate telecommunications links.


Navys is a flexible GNSS constellation simulator developed by Thales Alenia Space (Mission Software) and Elta (simulator) under contract to CNES.Its development was initiated in order to meet the growing needs of navigation laboratories.

ECP - Satellite Link Emulator

RF propagation channel simulator

The ECP is a satellite link emulator (SLE) designed to simulate the principle propagation phenomena occurring during the transmission of RF signals between the ground stations and satellites or other mobile devices, such as land vehicles, aircraft, missiles, etc.


The REM is a very high rate flexible modulator capable of delivering digital modulation signals of different types on 1 to 4 independent channels:

  • Linear (Pi/2-BPSK, Pi/4-QPSK, BPSK, QPSK, 8PSK, 3Pi/8-8PSK, 16APSK (with programmable radius ratio), 16QAM,
  • GMSK type 2 state continuous phase with programmable BT and states,
  • Optional OQPSK, 32APSK modulation (with programmable radius ratio).
