GPS02-UBX module features the u-blox M10 standard precision GNSS platform and provides exceptional sensitivity and acquisition times for all L1 GNSS signals. The extremely low power consumption in continuous tracking mode allows great power autonomy for all battery-operated devices, such as asset trackers, without compromising on GNSS performance.
GPS02-UBX module supports concurrent reception of up to four GNSS (GPS, GLONASS, Galileo, and BeiDou). The high number of visible satellites enables the receiver to select the best signals. This maximizes the position accuracy, in particular under challenging conditions such as in deep urban canyons. In the firmware described here,however, the number of concurrently received GNSS is limited to three. u-blox Super-S (Super-Signal) technology offers great RF sensitivity. It provides high sensitivity, high positioning accuracy, low power consumption and low cost positioning and navigation solutions for the manufacture of navigation and positioning terminal products such as vehicle, ship borne, handheld and wearable.

Module interface description
1) Power supply
The module has three power input pins (VCC, V_BCKP and VDD_IO) and one power output pin (VCC_RF).
VCC is the main power supply of the module.
VCC_IO is the IO power supply of the module.
V_BCKP is the backup input power supply of the module, which supplies power to the RTC circuit when the main power supply
VCC is cut off to ensure that key information is not lost, so as to realize the hot start function.
VCC_RF outputs 3.3V voltage value, which can be used to power the antenna or the external LNA of the module.
2) Antenna interface
The antenna interface (RF_IN pin) of the module can be directly connected to a multi-mode antenna. The interface adopts 50Ω impedance matching inside.
3) Reset interface
The module has its own power-on reset circuit. If the user does not use the external reset function of the module, the nRESET pin can be left floating; if the user uses the external reset function, the module can be reset after the VCC voltage stabilizes for 50ms. Keep for more than 1ms, the timing is as follows:
4) 1PPS signal interface
Module 4 pin 1PPS is the second pulse signal output, 1PPS signal needs to be delayed for several seconds after the module realizes positioning.
5) UART interface
The serial port outputs NMEA data at the UTC second boundary, and the host computer can also switch the module's working mode and baud rate through the serial port. The baud rate range supported by the module is 4800bps～921600bps. The default baud rate is 38400bps. The data format is: 1 start bit, 8 data bits, 1 stop bit, no parity bit.
