ISS To Be On the Air For JOTA :
If you are planning on participating in this weekend's Jamboree On the Air (JOTA), take note: Astronaut Mike Fossum, KF5AQG, is planning to participate in JOTA from the International Space Station, using the call sign NA1SS. According to the AMSAT website, Fossum’s schedule is somewhat flexible on the weekends, but he will not be available for every pass. The typical crew work periods are 0800-1930 UTC, but they are sometimes available a bit later. When available, Fossum will be operating on the standard ISS frequencies. In the US and elsewhere in IARU Regions 2 and 3, the uplink is 144.49 MHz. In Region 1, the uplink is 145.200 MHz. The worldwide downlink for NA1SS is 145.800 MHz.
India CubeSats :
Two university cubesats JUGNU and SRMSAT
JUGNU was developed by a team of students and faculty at IIT Kanpur and ISRO scientists to launch India's first Nano Satellite. The satellite's mission includes:
Micro Imaging System
GPS receiver for locating the position of satellite in the orbit
MEMS based IMU (Inertial Measurement Unit)
Jugnu Frequencies:
CW Beacon - 437.275 (17dbm)
Pay load - 437.505
At press time no further information was available for SRMSAT other than its payload down link and CW Beacon will transmit on 437.425 MHz(10dbm)
