test_dop.test_dop_across_time(navdata)[source]

Test DOP calculation across time is properly added to NAV data.

Parameters:

navdata (NavData) – A NavData with multiple timesteps (i.e., as in real data).

test_dop.test_dop_across_time_with_selection(navdata, which_dop)[source]

Test DOP calculation across time is properly added to NAV data.

Parameters:

  • navdata (NavData) – A NavData with multiple timesteps (i.e., as in real data).

  • which_dop (dict) – A dictionary specifying which DOP values to calculate.

test_dop.test_simple_dop(navdata, expected_dop)[source]

A simple set of satellites for DOP calculation.

Parameters:

  • navdata (NavData) – A NavData with only one time entry of a simple satellite scenario.

  • expected_dop (dict) – The expected dop values for the simple satellite scenario.

test_dop.test_simple_enu_unit_vectors(navdata, expected_los_vectors)[source]

A simple set of satellites for ENU unit vector calculation.

Parameters:

  • navdata (NavData) – A NavData with only one time entry of a simple satellite scenario.
