auto-scheduler

This is a tool to automatically compute passes of satellites on the SatNOGS network. It uses code from the SatNOGS network scheduler. It requires python-satellitetle for downloading TLEs.

Dependencies

sudo apt-get install libxml2-dev libxslt1-dev
pip install -r requirements.txt

Configuration

Copy the env-dist file to .env and set your legacy SatNOGS Network credentials.

Test run

Perform a test run to download orbital elements and transmitter priorities (these are stored in /tmp/cache) with

schedule_single_station.py -s <ground station ID> -n

The -n option computes the passes but does not schedule them. To schedule these passes, run

schedule_single_station.py -s <ground station ID>

Setup priority scheduling

The following commands will add a list consisting of all DUV, BPSK1k2, BPSK9k6, [G]MSK and [G]FSK transmitters into priorities_37.txt. Please change the station id (here 37 - in the cache file and the list file name) to your correspending one!

awk '{if ($3>=80) print $0 }' /tmp/cache/transmitters_37.txt | grep -e "FSK" | awk '{printf("%s 1.0 %s\n",$1,$2)} > priorities_37.txt'
awk '{if ($3>=0) print $0 }' /tmp/cache/transmitters_37.txt | grep -e "BPSK1k2" | awk '{printf("%s 1.0 %s\n",$1,$2)} >> priorities_37.txt'
awk '{if ($3>=0) print $0 }' /tmp/cache/transmitters_37.txt | grep -e "BPSK9k6" | awk '{printf("%s 1.0 %s\n",$1,$2)} >> priorities_37.txt'
awk '{if ($3>=80) print $0 }' /tmp/cache/transmitters_37.txt | grep -e "MSK" | awk '{printf("%s 1.0 %s\n",$1,$2)} >> priorities_37.txt'
sort -n -k 4 /tmp/cache/transmitters_37.txt | grep -e "DUV" | awk '{printf("%s 1.0 %s\n",$1,$2)} >> priorities_37.txt'

Add cron-job

Start editing your default user's cron (select your preferred editor):

crontab -e

Add a line like this - execute the scheduling script on each full hour:

0 */1 * * * <path_to_auto_scheduler>/schedule_single_station.py -s <station_id> -d 1.2 -P <path_to_priority_list>/<priority_file>.txt -f -z

Omit the -f option to also fill in the gaps, but be aware if using a rotator setup! This will wear-out your Rotator very quickly! Add -w 60 for a delay if you want to give your rotator a a bit of time (60 s) to reset or home.

Usage

The following command will list all available command-line arguments:

./schedule_single_station.py --help
