Why Use a Steptrack System?
The apparent stability of a geosynchronous satellite is defined
by its “stationkeeping window”. This “window” represents the
East-West (E-W) and North-South (N-S) travel limits that apply
to a satellite. Most domestic geosynchronous satellites are
maintained in a stationkeeping window of 0.1 degree.
As a satellite approaches the end of its fuel supply, the satellite
owner may seek to extend its useful life by shutting off the
North-South stationkeeping, permitting a controlled excursion
in the satellite orbit to preserve stationkeeping fuel.
