Iran’s Fajr satellite uses Ham Radio bands

*Nico Janssen PA0DLO* reports that the Iranian *Fajr* satellite has an
amateur radio band downlink on 437.538 MHz

On the AMSAT Bulletin Board Nico says that it carries a camera for Earth
observations and should have a telemetry downlink on 437.538 MHz and a
command uplink in the 144-146 MHz amateur radio band.

The Iranian satellite Fajr or ‘Dawn’ was launched on February 2, 2015 at
0850 UT from the Imam Khomeini Space Center which is south of Semnan in the
northern part of the Dasht-e-Kavir desert.

The 50 kg satellite was carried on a Safir launcher into an initial orbit
of 223 km by 470 km with an inclination of 55.5° and has been given an
object ID of 2015-006A 40387.

It is Iran’s fourth satellite and has propulsion in the form of a cold gas
thruster. Presumably the thruster will be used to circularize the orbit at
around 470 km which may give it a lifetime of over a year.
