GPSR and LRR (Swarm)
About GPSR and LRR
![GPS and LRR](/eogateway/documents/20142/1473152/GPS-LRR-overview.jpg)
Precise orbit determination relies on the data from GPS receivers (GPSR), which were developed by RUAG Space in Austria. Each Swarm satellite is also equipped with a Laser Retro-Reflector (LRR). The LRR is a passive payload that features four prisms to reflect short laser pulses back to the transmitting ground station.
Data Description
The Swarm mission delivers Level 1b and Level 2 data products. Data products are available from individual satellites on a daily basis or from the full constellation.
The data is freely available to everyone.
Swarm data products are also available by the thematic areas the mission supports:
- Swarm Core products
- Swarm Geodesy/Gravity products
- Swarm Ionosphere/Magnetosphere products
- Swarm Lithosphere products
- Swarm Mantle products
- Swarm Oceans products
- Swarm Space Weather products
- Swarm Thermosphere products
Learn more about the Swarm products in the Swarm Product Data Handbook. The handbook provides a detailed description of the products. It is a useful reference to support the use of Swarm products for further processing or applications.
