Beyond MEO
From GNSS-based navigation in lunar orbit to next-generation in-orbit geodetic observatories — emerging applications that push the boundaries of space geodesy and navigation.
GNSS for Lunar Missions
GNSS signals transmitted from Earth satellites reach far beyond their intended coverage — the weak side-lobe emissions that spill past the atmosphere can be used for positioning even near the Moon. This enables GNSS-based navigation at lunar distances, but the geometry is fundamentally different: shallow signal angles and a highly unfavorable constellation geometry make observability and estimability critical challenges.
- Simulation of side-lobe GNSS signal availability and geometry at lunar distances
- Observability & estimability analyses for this challenging multi-path geometry
- Sensor fusion studies — e.g. integration of GNSS with star trackers or other navigation aids
- Kalman filtering for near-real-time or onboard navigation solutions
- Consulting on weak-signal acquisition and receiver architecture considerations
In-Orbit Geodetic Observatory
Co-locating all four geodetic observation techniques — GNSS, SLR, VLBI, and DORIS — on a single satellite platform eliminates the terrestrial local-tie problem: instead of linking ground-based instruments through complex survey campaigns subject to thermal deformation and tectonic motion, the space tie is rigid and stable by design. This is a prospective field; missions of this type are planned for later this decade, with first data still years away.
- Pre-mission estimability & observability studies for multi-technique co-location
- Error characterization — bottleneck identification and parameter separability analysis
- Simulation of the combined measurement system and expected reference frame contributions
- Consulting on processing strategies using standard geodetic parameter estimation tools
