gps gnss module

The GNSS positioning modules developed by SKYLAB are divided into GPS module, BeiDou module, inertial guidance module, high-precision positioning module and so on according to the receiver type and functional characteristicsgps gnss module, and many novice engineers will be dumbfounded at the early stage of selection. It would be better if it can help you engineers to select GPS module and BeiDou module!

SKYLAB GNSS modules

GPS module, Compass module, inertial guidance module, high-precision positioning module differences.

the chip is not the same: the GPS module, BeiDou module, inertial guidance module, high-precision positioning module built-in chip launched by SKYLAB are not the same.

package size is not the same: SKYLAB's GPS module, Compass module, inertial guidance module, high-precision positioning module product line have a variety of modules, so the size of each module package is not the same.

the receiver type is different: GPS module only supports receiving GPS satellite signals; BeiDou module supports receiving GPS, BDS, GLONASS, GALILEO satellite signals, and supports multi-system joint positioning and single-system independent positioning; inertial guidance module is a combined navigation module supporting GNSS + INS, which supports both satellite positioning and inertial navigation positioning; high-precision positioning module is a GNSS module with built-in RTK algorithm, which supports GPS+Beidou joint positioning, and with Beidou ground-based augmentation base station, it can achieve centimeter and centimetre level positioning accuracy.

positioning performance is not the same: GPS module, BeiDou module, high-precision positioning module in a weak signal environment such as tunnels, parking lots and other scenarios is no way to achieve positioning, but support GNSS + INS inertial guidance module with high-precision six-axis inertial device, and mature inertial algorithm, no odometer or speed signal access, and no strict installation requirements, even in tunnels, garages and other environments can provide high-precision positioning for vehicles.

 positioning accuracy is not the same: GPS module, Compass module, inertial guidance module positioning accuracy is only to the meter level, high precision positioning module positioning accuracy can reach the decimeter level, centimeter level.

The above is the difference between SKYLAB GPS module, BeiDou module, inertial guidance module and high-precision positioning module, in addition to the definition and functional differences, the most obvious is actually the difference between the parameters, on the SKYLAB positioning module selection table, please determine the positioning module model according to your application needs!
