Background

We will need to use the SGP4 Progagator to get the CubeSats position in orbit.

Requirements

Set it up using this package (https://pypi.org/project/sgp4/) so that we can retrieve the current position of the CubeSat given the TLE data

• Checkout yarik/tle-data-api branch

• Update the branch with main via a rebase

• Move gs/positioning/tle.py to gs/backend/positioning/tle.py and work inside of the gs/backend/positioning directory (this so that there are no issues when the gs frontend PR gets merged in)

• Add tests to functions in the tle.py functions that can be unit tested:

  • calculate_checksum
  • convert_decimal_point_assumed
  • parse_tle_data

• Add a method to the TLEData class to return the data as a 2 line format

• Create a file called sgp4.py and work there for the rest of the

• Setup sgp4 to use accelerated mode

• Create a data class to hold the returned SGP4 data (see usage in the documentation for data returned)

• Make a function that takes in a TLEData object and datetime or julian date and returns the sgp4 progagator data as an most likely a custom object

• Add tests for functions/methods that can be unit tested in the python_test directory under a new positioning directory

Response format:

{
	"data" : [...telemetry data]
}
