ADMISSION
The ADMISSION project synergistically integrates several advanced technologies for space applications:
- Multi-constellation GNSS (GPS + Galileo)
- Multi-frequency GNSS (L1/E1 + L5/E5a)
- Hardware architectures based on COTS (Commercial Off-The-Shelf) components
- Multi-antenna systems for phase differential measurements
- Advanced attitude determination algorithms
- Capability for integration with precise orbit determination (POD) modules
This combination allows for a high-performance, scalable, and upgradeable system, capable of adapting to evolving GNSS constellations and space market needs.
The project fits into the rapidly growing New Space Economy market, particularly the segment of small satellites in low orbit (LEO). This sector is driven by the deployment of constellations for telecommunications, Earth observation, and data services, with hundreds of satellites expected to be launched annually over the next decade. Over 90% of these systems are developed by commercial operators, who require increasingly cost-effective, compact, and reliable solutions. In this context, ADMISSION targets primarily integrators and manufacturers of cubesats and microsatellites, offering a competitive solution for navigation and attitude control. The system also addresses the need to increase the reliability of onboard architectures, serving as a complementary sensor in multi-sensor systems and helping to reduce operational risk.
OVERVIEW
ADMISSION (Attitude DeterMInation Satellite miSsION) is an innovative GNSS subsystem designed for the accurate determination of the attitude of small satellites, particularly cubesats and microsatellites. The solution is based on commercially available (COTS) components and introduces a compact, low-cost, and low-power approach while maintaining high performance. The system uses multiple GNSS antennas and advanced algorithms to precisely estimate the satellite’s orientation, overcoming the limitations of currently used technologies (such as magnetometers and single-frequency systems). The result is a receiver capable of providing reliable data for autonomous attitude control, improving mission precision and increasing the resilience of onboard systems. The project involves the development and ground validation of a prototype with an intermediate technology readiness level (TRL 4–5), ready for subsequent industrialization and space qualification phases.
