SpatiX FindCM Service Platform Solution

FindCM Service Introduction

FindCM is a centimeter-level accuracy service platform developed by Qianxun SI. The high-presision system includes three parts: GNSS stations: Include GNSS receiver and antenna to track GNSS signals, receiver satellite raw observation data and upload data to hi-precison platform in real-time. Self-develped algorithm to process data from GNSS stations, generate and broadcast correction service, manage user and GNSS stations. Terminal device tracks GNSS signals and connect with high-precision platform for receiving correction data. The algorithm on terminal device calculates the high-precision...

FindCM Service Core Technology

FindCM Service Core Technology Support network algorithm with 300+ GNSS Qianxun SGR (Spatial grid reference) technology， stations, cover area 700,000 square kilometers support large number of users（20,000+） Long Baseline Distance Auto Reorganize Network Improved meteorological algorithm, extend the When stations are offline, the platform baseline from 60KM to 120KM, reduce the number will reorganize the network to provide seamless service *We support distributed deployment on multiple servers to support thousands of stations and millions of concurrent users.

Qianxun SGR Technology The ordinary VRS is difficult to handle large number of users. Once ther is a new user, the platform needs to create an individual VRS source. To handle large number of user, Qianxun divides the large area to a lot of small grids. Users in the same grid will use the same VRS source. If the grid doesn’t have any user, it won’t transmit data. The grid is small to ensure the service is accurate. And, with Qianxun intelligent algorithm, the service and accuracy are seamless when crossing different grids.

Redundant Design, High Reliability Correction data redundancy Support physical station and SGR/VRS automatically switch. Meet higher reliability requirements Connection protocol redundancy Support NTRIP and OSS protocols. For some applications, the terminal can integrate SDK to connect service. Algorithm redundancy Support RTK and PPP at the same time，provide service for large area.

Optional Ionospheric Solution Self-developed ionospheric optimization algorithm to effectively deal with active ionospheric problems Ionosphere monitoring and forecasting Quality factors：broadcast ionosphere related quality factors to guide terminal device to adjust the algorithm and improve the fixed rate and accuracy. Cannot fix due to active ionospheric problems Improved with quality factors

PPP via internet (NSSR) : For user who needs PPP service, FindCM service can meet the requirement. Without local stations, FindCM can use global stations to provide PPP-AR. With local stations, FindCM service • Converge time < 10S, horizontal accuracy 2.5cm • Individual base station failures do not affect overall service accuracy • Can better deal with active ionospheric problems • Smaller network comsuption

Optional AGNSS Service AGNSS Service Fasten the cold start time from 30s to 3s Support 5 mian constellations of ephemeris, almanac, clock error, ionosphere, UTC data... Supports the delivery of specified constellation and specified location data to save power

Other Advantages 300+ GNSS Stations Support network algorithm with 300+ GNSS stations, cover area 700,000 square kilometers 20,000+ Concurrency Qianxun SGR (Spatial grid reference) technology， support large number of users（20,000+） Ø BDS+GPS+GLONASS+GALILEO+QZSS Ø Linux based - stability 99.9% Ø Web based - easy access anywhere Ø Compatible with existing stations Ø Connect stations with NTRIP/TCP Ø Multiple datums and customizable Long Baseline Distance Ø Smart connection strategies Improved meteorological algorithm, extend the Ø User access limitation configurable baseline from 60KM to 120KM,...
