Hi All,

The launch time for the Nayif-1 CubeSat has been confirmed as 03:58UTC on February 15th 2017 on the PSLV C37 vehicle and a set of pre-launch TLEs have now been released:


1 17002U 17002A   17046.17824931 0.00000000  00000-0  00000-0 0  9993

2 17002  97.5521 107.5843 0004848 278.6481 296.8511 15.21991390    01

This file can also been downloaded from here http://download.funcube.org.uk/nayif_tle.txt

We expect that the FUNcube transmitter on Nayif-1 will activate at approximately 05:06UTC, but the exact timing is still to be confirmed!  Initial transmissions will be in “safe” mode and will be of the 1k2 BPSK telemetry only with approx 50mW of RF power. If the predictions are correct, the spacecraft will be heading north over Mexico and the western parts of the US and Canada.

During the Launch and Early Operation phase (LEOP) of the mission, the Nayif-1 command team will be headquartered at the American University of Sharjah Ground station in the United Arab Emirates. They will obviously be especially keen to have all possible reports of signal reception during this first orbit! To encourage everyone to take part, there will be a small prize for the station that submits the first data to the Nayif-1 Data Warehouse and perhaps an extra reward if they manage to receive the very first frame transmitted by the spacecraft! This should have the sequence number 5471 or 5472.

Details of the Nayif-1 frequencies, together with details of how to the download the Dashboard can be found here


The Data Warehouse is still under final development but a preview can be seen here: http://data.amsat-uk.org/nayif1/index 

Please note that if you are already a registered user of the FUNcube Dashboard then you do not need to re-register. Your existing details will transfer automatically to the new Dashboard when you run it for the first time.

If you run the test file with the Nayif-1 Dashboard please do not expect the Warehouse to show the data - it is from an earlier date than that is already displayed. However the “packets uploaded” tab at the bottom right corner of your Dashboard will show that the files have uploaded OK, that all is well with your system and that it is ready for action. 

We are hoping that the actual launch will be webstreamed and details of this will be made available as soon as possible.  The AMSAT-UK and -NL team will also be using the #funcube IRC channel 
on launch day and you will be very welcome to join them there. If you do not have the Dashboard available then please submit your heard reports here. A web client can be found at http://irc.lc/freenode/funcube if you do not have an IRC client installed.

73 and thanks for your support
