Advanced Satellite Link Emulator series
Polaris’ ASLE series is an advanced satellite link emulator designed to extend the propagation time delay of the PSLE series from 265ms to 530ms. The ASLE-L series operates in L-band and supports Doppler shift of up to -6MHz to 6MHz and operating bandwidth of up to 200MHz. The ASLE series provides an ideal solution for satellite modem testing, satellite to earth station RF link testing, spacecraft payload testing, and general testing systems using satellite communications.
The ASLE series is categorized into an IF band series and a L band series. The IF-band series operates at 70 MHz or 140 MHz, and the L-band series operates from 950 MHz to 1450 MHz (950 MHz to 1950 MHz optional).
● Time Delay
Reproduction for propagation time delay due to distance between satellite and earth station terminals
● Doppler Effect
Reproduction for doppler frequency shift between satellite and moving earth station terminals
● Attenuation
Reproduction for radio path loss due to heavy rain or heavy snow
Satellite Link Emulator series
The Polaris PSLE series is a Satellite Link Emulator for geostationary satellites. The PSLE series provides an ideal solution for satellite modem testing, satellite to Earth station RF link testing, spacecraft payload testing, and general testing systems using satellite communications. The PSLE series is categorized into an IF band series and a L band series. The IF-band series operates at 70MHz or 140MHz, and the L-band series operates from 950MHz to 1,450MHz (950MHz to 1,950MHz optional).
