GLONASS's orbit makes it especially suited for usage in high latitudes, where getting a GPS signal can be problematic.

FactSnippet No. 793,934

All GLONASS satellites transmit the same code as their standard-precision signal; however each transmits on a different frequency using a 15-channel frequency-division multiple access technique spanning either side from 1602.

Civilian GLONASS used alone is therefore very slightly less accurate than GPS.

FactSnippet No. 793,940

On high latitudes, GLONASS' accuracy is better than that of GPS due to the orbital position of the satellites.
