Positioning satellite · SBAS (augmentation)
ASTRA 5B
Live position of ASTRA 5B, propagated with SGP4. A GEO satellite of SBAS (augmentation), catalogue number 39617, period about 1436.1 minutes, inclination 0.09 degrees. To find out whether it is above a given place on the ground, use KUON SKY.

An equirectangular world map. The thin line is one full orbit of ground track; the bright ring is the area from which this satellite stands above the horizon.

Elevation is the angle above the horizon. The closer to 90 degrees, the more nearly overhead it is, the shorter its path through the atmosphere, and the less likely a building or hill is to cut it off. To count with terrain shadow included, use KUON SKY.

About this system
These satellites carry corrections rather than providing positioning of their own. They broadcast values that cancel part of the error in GPS and other systems.
The regional services are WAAS (North America), EGNOS (Europe), MSAS (Japan), GAGAN (India), SDCM (Russia) and SouthPAN (Australia and New Zealand).
Most broadcast their corrections on L1 and L5.
About the numbers on this page
- Identity and orbit shape are computed from the orbital elements (OMM) published by CelesTrak. They describe the orbit at the element set epoch; the real orbit drifts slowly away from it.
- A satellite launched recently is still moving toward its assigned slot, so its values change from day to day.
- The live position is an SGP4 prediction. Whether the satellite is actually broadcasting a usable signal cannot be told from this calculation.
- The orbit class is decided mechanically from period and inclination, so it may not match the operator's own wording.
