A: While GPS satellite faults have always been infrequent, they have become rarer in the past decade due to the maturity of the GPS constellation and its Operational Control Segment (OCS). Lessons learned from past GPS satellite failures have also aided the development of newer GNSS constellations such as the European Galileo.

Ansys says the latest version of its Orbit Determination Tool Kit (ODTK), which provides highly accurate spacecraft orbit estimates, is better suited to operating near the moon and in “cislunar space,” the region between the Earth and the moon where orbiting spacecraft are influenced by the gravity of both bodies.

A: Many forms of differential GNSS (DGNSS) exist to provide GNSS users with corrections to their pseudorange and carrier-phase measurements along with information to support their applications and provide integrity assurance [1].

In this column, guest contributor Mike Horton from ANELLO Photonics introduces a new gyro technology that bridges the market gap between high-performance (but expensive) sensors (fiber-optic and ring laser gyros) and low-cost (but imprecise) MEMS gyros. Benefits of improved gyro quality enabled by SIPHOG are illustrated, including GNSS-denied navigation scenarios.

After years of studying the concept of using low-Earth orbit (LEO) navigation satellites to supplement the Galileo system, the European Space Agency (ESA) is ready to move forward with an in-orbit demonstration as part of its new FutureNAV program.
