Abstract
A system or method for generating or distributing GNSS corrections can include or operate to: generate a set of corrections based on satellite observations, wherein each correction of the set of corrections comprises an area associated with the correction, a tag, and correction data; update a set of stored corrections with the set of received corrections based on a tag associated with each correction of the set of stored corrections and the tag associated with each correction of the set of received corrections; and transmit stored corrections of the set of stored corrections to the GNSS receiver when the area associated with the stored corrections matches the locality of the GNSS receiver.
Claims20
A system for distributing corrections to a GNSS receiver comprising:
- a corrections generator configured to generate a set of corrections based on satellite observations associated with a set of satellites measured at a set of reference stations, wherein each correction of the set of corrections comprises:
- an area associated with the correction;
- a tag;
- and
- correction data;
- a gateway configured to:
- the set of corrections;
- and
- a set of stored corrections with the set of received corrections based on a tag associated with each correction of the set of stored corrections and the tag associated with each correction of the set of received corrections;
- and
- a distribution module configured to:
- to a GNSS receiver;
- determine a locality of the GNSS receiver;
- and
- transmit stored corrections of the set of stored corrections to the GNSS receiver when the area associated with the stored corrections matches the locality of the GNSS receiver.
