This actually still look at your specific application is what, according to the actual type of application to choose the GPS module, GPS module performance will be better. For example:
SKYLAB GNSS module
SKYLAB's GNSS module according to the support of satellite signal band, divided into single-frequency GPS positioning module, single-frequency Beidou positioning module and single-frequency Beidou multi-mode positioning module, dual-frequency Beidou multi-mode positioning module; according to the different positioning accuracy is divided into the standard high-precision GNSS positioning module and RTK high-precision GNSS positioning module; according to use of the GNSS module, the GPS module will be better. GNSS positioning module; according to the different ways of use is divided into embedded built-in GNSS positioning module and external antenna integration GNSS G-mouse finished products; according to the different performance of the module is divided into the standard high-precision GNSS positioning module, RTK high-precision GNSS positioning module, weak-signal GNSS + INS inertial combination of navigation modules and GNSS timing module.
Standard high-precision positioning navigation: from mobile Internet to Internet of Things, location is a basic indispensable information, the car driving on the road, you need to judge their own position in real time, and use the built-in standard high-precision GNSS positioning module to obtain the location information, with electronic maps to achieve navigation, it can easily and accurately tell the driver to the destination of the shortest or fastest path. SKYLAB has developed and launched SKG09A/SKG09BL/SKG09D/SKG09F standard high-precision positioning modules, as well as BeiDou 3 positioning module SKG1223, dual-frequency positioning module SKG122S/SKG122Y, and antenna-integrated GNSS module SKM80F/SKM81F/SKM51F/SKM2105FR, which can be used for vehicle management systems, security systems, and other applications.
RTK high-precision positioning and navigation: with the arrival of the new infrastructure boom, with the east wind of 5G + new infrastructure, driverless, self-driving and other technologies are being gradually improved, for intelligent driving cars, the lanes are very narrow, and the distance between the obstacles on the roadside is also shorter. This means that the car's requirement for positioning accuracy is 10 to 30 centimeters.SKG12UR, the RTK high-precision positioning module developed and launched by SKYLAB, has a built-in RTK algorithm, and also supports BDS and GPS dual satellite positioning system, with the high-precision positioning service of the national Beidou augmentation network, it can achieve real-time centimeter-level positioning accuracy, which can satisfy the high-precision positioning needs of smart bo agriculture and smart driving cars. Positioning demand.
Weak Signal Inertial Combination Navigation: When a car is traveling on the road, its view may be blocked by surrounding trees, trucks, and urban buildings, and the satellite navigation system is susceptible to the influence of the surrounding environment, such as trees and buildings, resulting in a multi-path effect, which reduces the accuracy of the positioning results and even makes them lost, especially in the tunnels or indoor environments, where the satellite navigation system is basically unavailable. SKYLAB weak-signal inertial combined navigation module SKM-4DU/SKG121D provides real-time high-precision vehicle positioning, speed measurement and posture measurement information. When the signal accuracy of GNSS system is reduced or even satellite signal is lost, without the help of odometer information, using pure inertial navigation technology, it can also be used to carry out high-precision positioning, speed measurement and posture measurement of the vehicle carriers in a longer period of time to solve the problem of vehicle positioning drifting or inability to use a weak signal in a weak signal environment.
GNSS timing module high-precision timing: in order to achieve automation, intelligence, any application scenarios involving various sub-systems working in concert need time synchronization, electric power, rail transportation, communications, base stations, as well as financial and other market capacity of about 10 billion. Extremely low latency scenarios such as autonomous driving and telemedicine require even higher time synchronization accuracy. SKYLAB's composite GNSS timing modules SKG09DT/SKG12DT and high-precision GNSS timing module SKG121T are able to meet the time synchronization needs in Telematics.
