Monthly Station Performance Assessment
October 1, 2023 through September 30, 2024
Please note the following:
- On maps that depict performance with differently sized "bubbles", the size of the bubble does not reflect coverage of what's tracked but to what extent the parameter is met.
- Stations that are not capable of ranging to GNSS are not assessed on GNSS parameters; furthermore, these stations are not assessed on their compliance to the ILRS priority list because the list includes GNSS satellites.
