HOLUX Three Generations of GS-R238 SIRF Bluetooth GPS Receiver

Product Description

GS-R238 has built removable and rechargeable lithium battery, satellite antenna, Bluetooth transmit / receive system, and by the United States SiRF (SiRF) designed by the company's third-generation low-power GPS receiver chips, with full location capabilities, to meet the stringent requirements of professional orientation and personal consumption demand. GS-R238 is a dual-purpose satellite receiver. Can interface with a Bluetooth PDA, notebook computers and other devices with satellite data transmission purposes, can also be transferred through the appropriate cable, as a general GPS receiver, do not send the satellite signal to a device with Bluetooth transmission interface use.

GS-238 from the application of car navigation, security systems, map making and survey to agricultural uses. With Bluetooth devices, RS-232 or USB-compliant interface to communicate with other electronic equipment, and built-in rechargeable batteries, storage of satellite data such as satellite signal status, the last record location, date and time.
Specifications, GS-238 using third-generation low-power chip SiRF Star III, has quickly locate and track 20 satellites, the 200,000-chip / frequency hardware to improve satellite signal receiving and transmitting the search. GS-238 is also fully compatible with the Bluetooth specification defines the serial port (Serial Port Profile (SPP). It is built-in style and the removable rechargeable lithium ion batteries unloaded, users do not need external power supply, the use of satellite can be separate positioning system at least 9 hours. GS-238 built-in rechargeable lithium battery-type backup, store and RTC satellite positioning data, positioning to accelerate the next time. It supports NMEA0183 2.2 version or SiRF output data format.

Introduction:
Scope from the car navigation, security systems, map making and survey to agricultural uses. Use only the basic needs "appropriate in the face of the sky." With Bluetooth devices, RS-232 or USB-compliant interface to communicate with other electronic equipment, and built-in rechargeable batteries, storage of satellite data such as satellite signal status, the last record location, date and time.

GS-R238 low power consumption, and can simultaneously track 20 GPS channels, each 0.1 seconds to receive the first, second update location information. With a power-saving mode (Trickle-Power) function, so that positioning the work can only perform part-time. Also provides a normally off state at the reception, then set the time to start the regular orientation (Push-to-Fix) function.

Features:
1. Using third-generation low-power chip SiRF Star III.
2. Has quickly locate and track 20 satellites.
3. Chipset built-in 200,000 time / frequency hardware to improve satellite signal receiving and transmitting the search.
4. Is fully compatible with Bluetooth Serial Port Definition (Serial Port Profile (SPP)).
5. Low power consumption. Built-in rechargeable lithium-type batteries and the removable unloaded, users do not need external power supply, satellite positioning systems can be used independently for at least 9 hours.
6. Built-in rechargeable lithium battery-type backup, store and RTC satellite positioning data, positioning to accelerate the next time.
7. Supports NMEA0183 2.2 version or SiRF output data format.
8. Flash Memory (FLASH) stored procedures can be through the serial port, update the internal system procedures.
9. To provide multi-function extension terminal, even if the system devices without Bluetooth device can also be connected to enjoy.
