General Description

    The SkyLab SKM51 Series with embedded GPS antenna enables high performance navigation in the most

stringent applications and solid fix even in harsh GPS visibility environments. 

     It is based on the high performance features of the MediaTek single-chip architecture, Its –165dBm tracking

sensitivity extends positioning coverage into place like urban canyons and dense foliage environment where the GPS was not possible before. The connector design is the easiest and convenient solution to communication with other electronic equipment.

Features

  Ultra high sensitivity: -165dBm

  22 tracking/66 acquisition-channel receiver

  WAAS/EGNOS/MSAS/GAGAN support

  NMEA protocols (default: 9600bps)

  Internal back-up battery

  Embedded patch antenna 25 x 25 x 4.0 mm

  Operating temperature range: -40 to 85

  RoHS compliant (Lead-free)

  Tiny form factor :50.5* 38.5 * 18mm

 

Applications

  LBS (Location Based Service)

  PND (Portable Navigation Device)

  Vehicle navigation system

  Mobile phone

    Hardware Interfaces Configuration Power Supply: Regulated power for the SKM51 series is required. The input voltage Vcc should be 3.3V~5V,current is no less than 150mA. Suitable decoupling must be provided by external decoupling circuitry(10uF and 1uF). It can reduce the Noise from power supply and increase power stability.

    UART Ports: The SKM51 series supports one full duplex serial channels UART. The serial connections are

at 2.85V LVTTL logic levels, if need different voltage levels, use appropriate level shifters. the data format is

however fixed: X, N, 8, 1, i.e. X baud rate, no parity,eight data bits and one stop bit, no other data formats are

supported, LSB is sent first. The modules default baud rate is set up 9600bps.

    RS232 Ports: The SKM51 series uses single-chip RS232 to UART bridge, It is 3V powered EIA/TIA-232

and V.28/V.24 communication interfaces with low power requirements.
