In 2021, P-10 Pro professional HD GNSS data logger has been launched. It is equipped with the most advanced dual-frequency positioning technology, which increases the positioning accuracy by 5 times. It reaches the sub-meter level for the first time, satisfying professional users' pursuit of an ultra-high-precision track!
GNSS products are widely used, but the single-frequency L1 products have a bottleneck: low positioning accuracy that is difficult to improve. The new L5 frequency has come as a response to the shortcomings of single-frequency L1 and demands for higher positioning!
Multi-constellation positioning capability
GNSS stands for Global Navigation Satellite System.
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.
Compared 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.
What is dual-frequency L1+L5?
Dual-frequency L1+L5 positioning refers to a technology that uses both the L1 frequency and the L5/E5a frequency of the GNSS system.
The frequency of the L1 band is 1575MHz, and the figure for L5 band is 1176MHz. The wavelength of L5 is longer, and the attenuation during transmission is smaller. 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.
P-10 Pro is equipped with dual-frequency L1+L5 and built-in L1+L5 dual antennas. Compared with single-frequency GPS products, it has its positioning accuracy improved from 2.5 meters to 0.5 meters.
Among the professional data loggers, P-10 Pro is the first to achieve sub-meter positioning accuracy.
Effectively eliminate Ionospheric and multipath interference
Compared 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, which supports dual-frequency L1+L5, can simultaneously monitor signals on two different frequencies on the same satellite, compare and analyze the data, and correct ionospheric delay to eliminate errors caused by the atmosphere.
In challenging environments (such as urban canyons, high-rise buildings and places covered by trees), satellite signals become messy after being reflected by buildings and intertwined with the correct direct signals, and the equipment has a large positioning accuracy error in this case, i.e. the multipath effect. Dual-frequency technology can distinguish the real signal from the signal reflected by the building, thereby reducing errors caused by multipath effects.
“Overall, the multi-constellation, dual-frequency receiver provided more robust and accurate positional solutions compared with single-frequency smartphones.”*

P-10 Pro is an epoch-making HD GNSS data logger.
It can achieve lane-level positioning accuracy in the open air, and boasts a number of excellent anti-interference abilities in a challenging environment.
P-10 Pro is more stable, more accurate, more professional!
What does the HD GNSS of P-10 Pro refer to?
High Definition Global Navigation Satellite System. It refers to the high-precision positioning performance that P-10 Pro can provide: Horizontal direction 0.5m/CEP(50%); 1.5m/CEP(95%). It boasts lane-level positioning accuracy.
CEP refers to Circular Error Probable. 0.5m/CEP(50%)* means that the probability of the track points falling within a 0.5m radius is greater than 50%; 1.5m/CEP(95%)* means that the probability of the track points falling within a 1.5m radius is greater than 95% .
P-10 Pro also has high absolute altitude accuracy with an error of only ±15 m *, comparable to the altitude measurement ability of a barometer.

Static drift test
Test purpose: To evaluate the static drift suppression performance of the receiver (P-10 Pro config file parameter: Speed mask=OFF).
Test duration: 4 hours
Location: On the roof of the building, P-10 Pro is placed face up, and the GNSS status lamp is blue.
Surroundings: In a 50m radius, there are no objects higher than above-mentioned location.
Walking track test
Test purpose: Walk around the outer circle of the tennis court and return to the start point to evaluate the accuracy of the track at an ultra-low speed.
Test time: UTC 2021-10-20 15:23 | Average speed: 3.5km/h
Location: P-10 Pro is held in hand, face up, with a certain distance from the body, and the GNSS status lamp is blue.
Surroundings: Open sky, with no buildings blocking the vision nearby.
Low-speed driving track test
Test purpose: Record three consecutive times along the same route to evaluate the smoothness of the low-speed driving track.
