(PDOP <= 6) on day interval: the elevation angle of not less than 5 degrees.
Date: 04.04.2011.
Are used for their intended purpose 22 SC (1,2,3, .5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20, .22,23,24)

Integral accessibility globally: 99.3%
Integral affordability Russia: 100.0%

Notes: 1. White color indicates areas with 100% foreign availability of GLONASS navigation system for the current day.
2. Availability is calculated based on the current almanac for the day interval as the percentage of time during which the condition PDOP <= 6 for elevations SC> = 5 degrees where PDOP — position (three-dimensional), a geometric factor. Readability calculation: time — 4 minutes, and the surface of — 1 degree.
