Is there a GLONASS receiver in your future? You may be more motivated if you live at a northerly latitude. A Swedish firm, Swepos, which demands one-meter accuracy for their work, has integrated the Russian system into their operations, saying…
"It functions somewhat better at northern latitudes because its satellite orbits are located higher in the sky and we see them better than we do the GPS satellites," said Bo Jonsson, deputy head of a geodesic research unit at Swepos.
Improved reception and accuracy is more important for high-precision users, and I don’t know how much advantage this would offer for consumer-grade units, but I do expect to see dual GPS-GLONASS units in the near future.
