The RinexNavFile object provides the capability to read and write Broadcast Ephemeris data to and from a Rinex Navigation file. This is an ASCII file of Broadcast Ephemeris data conforming to the RINEX standard. FreeFlyer supports the RINEX 2 and RINEX 3 formats.

RinexNavFiles (also known as Broadcast Ephemerides) contain position, velocity, and clock information for some Global Navigation Satellite System (GNSS) constellations. The GPS and Galileo constellations both use the RINEX format. FreeFlyer has the ability to read and write RinexNavFiles, but cannot generate new data in this format (Broadcast Ephemeris data can be read in and then written out to a new file, but cannot be simulated independently). The time system is GPS Time, and positions and velocities are in the ECEF reference frame, which FreeFlyer converts into the ICRF frame.

Note: Due to its discontinuous nature, Broadcast Ephemeris data should not be used to propagate Spacecraft objects while detecting events using Interval Methods. Instead, the Broadcast Ephemeris should be used to set the initial state of the Spacecraft and then an integration-based propagator, such as an RK89 or Cowell integrator, should be used to propagate it.

More information on the RINEX format can be found in several locations. Two example references are provided below:

Additionally, historical RinexNavFiles and pre-processing utilities can be downloaded from multiple sources; four examples are provided below:

An example of the format of a RINEX 2 Nav file is given below.

In the diverse landscape of independent visual novels, few titles manage to capture a sense of pure energy and unbridled positivity quite like KIRSCH VIRCH (キルシュヴァーチ) . Developed by the creative team at LOST RARITIES

The game utilizes a narrative-driven format where player choices can influence the progression of the story and the outcome of specific relationships.

An example of the format of a RINEX 3 Nav file is given below.
