Additional Notes:
1Please contact SonTek for accuracies better than 1%, or velocities >10 m/s.
2Standard AA batteries are defined as alkaline or NiMH rechargeables, with a diameter up to 14.5mm.
3High power may not be available in all countries; all ranges with default 2 dBi antenna and line-of-sight.
4Requires absolute RTK solution. Only available with HYPACK software.
5Depends on multipath environment, antenna selection, number of satellites in view, satellite geometry, and ionospheric activity.
