Merry Christmas and Happy New Year 2012!
My country - the birthplace of the GLONASS. I speak English badly. Yesterday I compared the two navigation devices: GLONASS/GPS Samsung Galaxy Note on BCM47511 chip and BT GPS Navitel RX200BT on SirfStar III chip. Tracks were recorded synchronously in NMEA format. I drove the route in the morning and evening.
Legend:
Blue - Samsung Galaxy Note
Red - Navitel RX200BT
On the morning Samsung is less accurate (10 meters shift from GPS track):
When RX200BT took 12 GPS satellites, Note, not more than 10.
After analysing logs I concluded: Note have 18 channels - 10 for GPS and 8 for GLONASS.
In the evening i take best result for GLONASS:
YOUTUBE: Samsung Galaxy Note (Blue) vs Navitel RX200BT (Red)
Too different results.
Result of GPS/GLONASS Galaxy Note is badly: 19 meters
Only GPS is very good (8 meters):
Why GLONASS/GPS less accuracy, but only GPS system is best?
