All,
While waiting for a TLE set for Nayif 1 from the JSpOC, I constructed a TLE set based on measurements on a number of passes since launch. This set is accurate to within 2 seconds and should remain accurate in the coming days.
NAYIF 1 1 60000U 17008XX 17051.92295152 .00001762 00000-0 80428-4 0 9993 2 60000 97.5107 113.5513 0006476 260.5747 99.4743 15.22401676 842
This TLE set can also be downloaded here: http://hamsat1.home.xs4all.nl/NAYIF1.txt
The actual frequency of the telemetry beacon of Nayif 1 is 145.9385 MHz. There is virtually no temperature drift on the beacon frequency.

Hi Nico,
Thanks for this.
For educational purposes, I’d love to read an article from you about how you went about doing that.
Cheers, Kevin KK6NHN

Spot on!! Hit the bird with 5 watts into an Eggbeater and didn't have to adjust the uplink at all! Worked WB8RJY 5 and 9.

Hi Nico,
Many thanks for your work and the detailed analysis over the past few days.. the team are very appreciative!

Hi Nico,
This arrived after my E-mail to the BB. You are right, we have concluded the same. I am still checking with the other teams if they have anything near this object that fits, but chances are high that this object is correct.
Thanks
Wouter
