Compared with single-frequency GPS products, it has its positioning accuracy improved from 2.5 meters to 0.5 meters.Īmong the professional data loggers, P-10 Pro is the first to achieve sub-meter positioning accuracy.Įffectively eliminate Ionospheric and multipath interferenceĬompared with single-frequency, dual-frequency can effectively eliminate ionospheric errors and counter multipath effects, both of which are major factors behind errors in GNSS positioning accuracy. P-10 Pro is equipped with dual-frequency L1+L5 and built-in L1+L5 dual antennas. The signal strength of L5 is 6dB (4 times), higher than that of L1, while the chip rate of L5 (10.23MHz) is 10 times that of L1, and the ranging accuracy is also increased tenfold. The wavelength of L5 is longer, and the attenuation during transmission is smaller. The frequency of the L1 band is 1575MHz, and the figure for L5 band is 1176MHz. P-10 Pro supports multi-constellation in the world: GPS L1 and L5 GLONASS L1 Galileo E1 and E5a BeiDou B1 QZSS L1 and L5 IRNSS L5.Ĭompared with the single-constellation GPS positioning system, the GNSS multi-constellation positioning system can ensure rapid and effective positioning at any location in the world, while improving positioning accuracy and reliability.ĭual-frequency L1+L5 positioning refers to a technology that uses both the L1 frequency and the L5/E5a frequency of the GNSS system. GNSS stands for Global Navigation Satellite System. Multi-constellation positioning capability The new L5 frequency has come as a response to the shortcomings of single-frequency L1 and demands for higher positioning! GNSS products are widely used, but the single-frequency L1 products have a bottleneck: low positioning accuracy that is difficult to improve. For the first time, low cost and ultra-high-precision position logging become possible! It reaches the sub-meter level accuracy without compromising the cost of ownership. Instead, Columbus P-10 Pro uses the most advanced dual-frequency(L1 and L5 bands) positioning technology, which increases the positioning accuracy by 5 times.
