The global navigation satellite system (GNSS) is vital to modern technology, providing users accurate position and timing data. NTS-3, the first US experimental position timing and navigation (PNT) satellite in over 40 years, will explore new technologies to improve GNSS pushing current performance limits. Precision timing is a crucial technology for GNSS. The atomic clocks on board NTS-3 will be closely monitored, investigating methods to improve timing accuracy to more closely match clock performance in the ground. Moreover, single event upsets, anomaly detection and on board ensembling will be investigates. We outline a series of experiments, designed to test these new methods to improve the GNSS reliability and resiliency for use by future generations.
