By default, PSAT satellite, a.k.a NO-84, is not listed in Gpredict software, even you perfom the TLE updates. This can be solved if you save two files in the data space created by Gpredict in your user profile folder.

So, create a new text file, called 40654.sat and put inside the following content, representing the TLE data of this satellite:

[Satellite]

VERSION=1.1

NAME=PSAT

(NO-84)NICKNAME=PSAT

TLE1=1 40654U 15025D 19115.42507966 .00007101 00000-0 10468-3 0 06008

TLE2=2 40654 054.9901 060.1145 0140114 185.3000 174.6575 15.46199418104057

STATUS=0

Then, save this file and copy it in the folder

[user_profile_folder]\Gpredict\satdata,

where [user_profile_folder] is the location of your Windows profile and could be C:\Documents and Settings\your_user_name in Windows XP or C:\Users\your_user_name in further Windows versions (7, 8 or 10).

Then, create the second file, called 40654.trsp and insert the below content, representing the information about the PSAT transponders and frequencies:

[1k2 AFSK TLM]

DOWN_LOW=145825000

MODE=AFSK1k2

BAUD=1200

[APRS Digipeater]

UP_LOW=145825000

DOWN_LOW=145825000

MODE=AFSK1k2

BAUD=1200

[PSK31 Transponder]

UP_LOW=28120000

DOWN_LOW=435350000

MODE=PSK31

[Drifted PSK Transponder]

UP_LOW=28120000

DOWN_LOW=435347000

MODE=PSK31

Save this file and copy it in the folder [user_profile_folder]\Gpredict\trsp.

Finally, start the Gpredict application, perform a TLE update and search for PSAT in the satellites list.
