¹ Hot start (typical). Cold start < 40 s (typical).
² The tracking capability for a specific satellite system is based on publicly available information. For cases where public information is subject to change or not yet available Leica Geosystems cannot guarantee full compatibility.
³ Hardware ready for: GPS L1P(Y), GLONASS L1P, L5 CDMA, QZSS L6, NavIC L1 and SBAS L5 may be provided through future firmware upgrade
⁴ Designed for BeiDou Phase 2, Phase 3 compatibility.
⁵ Measurement precision, accuracy in position and height, reliability and time for initialisation are dependent upon various factors including the number of satellites tracked, the observation time, the ephemeris accuracy, the atmospheric conditions, multipath and resolved ambiguities. Figures quoted are RMS (root mean square) and assume normal to favourable conditions.
⁶ 100Hz ready. Can be provided through future firmware upgrade.
