Student CubeSat will have SSB/CW transponder

A student CubeSat project Nayif-1 is expected to launch this year, it
will provide an amateur radio linear transponder for SSB/CW
communications

Nayif-1 is an educational single CubeSat project with the goal of
providing an actual space project for Emirati University students.
Additionally it is intended to enthuse and educate young people about
radio, space physics and electronics.

The 1U CubeSat is a collaboration between the Mohammed Bin Rashid
Space Center and the American University of Sharjah both in the United
Arab Emirates.

The spacecraft will only require simple ground station antennas and an
SDR dongle receiver. This will make it uncomplicated for schools and
colleges to use with their students.

It is anticipated Nayif-1 will be launched into an elliptical, sun
synchronous, Low Earth Orbit (LEO) about 400 by 750 km. In such an
orbit the satellite passes over the Emirates at least twice a day.
This would allow the morning passes to be used for educational
purposes and the evening passes for Amateur Radio communications.

The student team will develop and operate a special ground station for
this spacecraft. They will also be developing a unique “Dashboard” to
display the received telemetry data and greetings messages in Arabic.

Nayif-1 will incorporate a novel autonomous attitude determination and
control system. This will be the first flight of this system.
Additionally it will carry a UHF to VHF linear transponder (FUNcube-5)
that will have up to 0.5 watt output and which can be used by Radio
Amateurs worldwide for SSB and CW communications.

A launch is planned for late 2015 on a SpaceX Falcoln 9.

IARU coordinated frequencies for NAYIF-1:
• 145.940 MHz 1200 bps BPSK FUNcube beacon
• 500 mW inverting SSB/CW linear transponder
– 435.045-435.015 MHz Uplink
– 145.960-145.990 MHz Downlink
