Es’hail 2 is a geostationary satellite which will carry two amateur radio transponders.

The launch of the Es’Hail-2 satellite into a geostationary orbit is currently planned for the 3rd quarter of 2017. The coverage area of the Narrowband (NB) and Wideband (WB) transponders should extend from Brazil to Thailand.

The two “Phase 4” amateur radio non-inverting transponders will operate in the 2400 MHz and 10450 MHz bands. A 250 kHz bandwidth linear transponder is intended for conventional analogue operations and an 8 MHz bandwidth transponder for experimental digital modulation schemes and DVB amateur television.

Narrowband Linear transponder
 2400.050 -  2400.300 MHz Uplink Right Hand Circular Polarization
10489.550 - 10489.800 MHz Downlink Vertical Polarization

Wideband digital transponder
 2401.500 -  2409.500 MHz Uplink Right Hand Circular Polarization
10491.000 - 10499.000 MHz Downlink Horizontal Polarization

A LEILA-2 system, similar to LEILA flown on AMSAT OSCAR-40 (P3-D) will be used for Traffic Control and Telemetry Beacons. The mayor difference is, that this is a ground-based system which will be installed at the Es’hailSat Satellite Control Center (SCC) near Doha in Qatar.

LEILA-2 will analyze the downlink power levels in the passband of the NB-transponder and automatically generate a Siren to remark users to decrease their uplink power.

LEILA-2 is a joint development of AMSAT-DL’s Achim Vollhardt DH2VA and AMSAT-UK’s Howard Long G6LVB.

LEILA is an German acronym for “LEIstungs Limit Anzeige”, which means: Power Limit Indicator.
