Deploying and Demonstrating Navigation Aids on the Lunar Surface [1]
[]
Date: 2023-11
Over the course of the transit to the Moon from Earth and during its the nominal lunar surface operations, LN-1 will broadcast its state and timing information back to Earth. Once it lands on the lunar surface, the payload will enter into a 24/7 operational period, and will also provide a navigation reference signal back to Earth. To validate LN-1 capabilities, DSN ground stations will be used to capture measurements and measure performance. Upon reception of the LN-1 data, high-accuracy packet reception timestamps will be used (along with atmospheric data for induced delays) to assess a ranging observation. This data will be captured during multiple passes to compute a navigation state of the payload during the mission. The LN-1 team is also partnering with other NASA researchers to collect Very Long Baseline Interferometry observations of the navigation signals as an independent truth reference.
