GPS Satellite Health Information
| Number of GPS satellites in the latest almanac: | 31 |
| Number of unhealthy GPS satellites in the SOF: | 1 |
| Current number of healthy GPS satellites: | 30 |
| Unused PRN number(s): | 25 |
This graph plots the number of healthy GPS satellites since 1998 (Full History),
or over the last year.
The number of healthy GPS satellites is the difference between the number of GPS
satellites in the almanac for that day,
minus the number of outages for that day. Note that since this is
calculated on a day boundary, this graph will show sequential outages in a single
day as concurrent, and may not reflect the more updated statistics above.
