It tracks up to 20 satellites for fast positioning and low power consumption, all in a compact, waterproof design. The rechargeable battery sustains internal clock and memory, while users can adjust power-saving settings for maximum efficiency. LED indicators provide clear status updates, making it an ideal choice for professionals on the go. ## Description This positioning application meets strict needs such as car navigation, mapping, surveying, security, agriculture and so on. Only clear view of sky and certain power supply are necessary to the unit. It communicates with other electronic utilities via compatible dual-channel through USB interface and saves critical satellite data by built–in backup memory. With low power consumption, the GR-213U tracks up to 20 satellites at a time, re-acquires satellite signals in 100 ms and updates position data every second.

Other than that it works well Review: Excellent and reliable GPS. - I have been using this Holux GR-213U USB GPS receiver for the past two years. I have found it to be of excellent production quality (Made in Taiwan), truly durable and waterproof as stated and has a convenient and strong magnet embedded in the base that allows it to adhere most any iron or steel surface. From a technical point of view, it contains the bullet-proof SiRF-Star III chipset specifically designed for receiving the US constellation of GPS Satellite signals. This is one of the best chipsets in the business -- no Russian GLONASS or Chinese GPS support in this chipset. Later models are based on a different chipset that supports both US and Russian satellites. However this unit works great! Driver software supplied emulates a serial port allowing compatibility with a huge range of GPS software. It also supports the industry standard NMEA (National Marine Electronics Association) command set for programming and additional functions can be invoked including the ZDA (1 pulse per second time signal). This also makes it useful for many purposes including serving as an accurate time source for many applications requiring time sync including Amateur radio JT65 and WSPR use. The package comes attractively boxed with all software on a mini CD ROM and adequate instructions plus some velcro and a suction cap to anchor down the lead in your application. I found that the driver was compatible with many 3rd party GPS programs supporting the NMEA protocol. LED flashes when sync is achieved, usually about 10 seconds after connecting to the computer. It does everything that I expect from a USB powered GPS unit. ## Features - SiRFstarIII chipset with embedded ARM7TDMI CPU available for customized applications in firmware - High performance receiver tracks up to 20 satellites while providing first fast fix and low powe consumption;Compact design ideal for applications with minimal space. - A rechargeable battery sustains internal clock and memory. The battery is recharged during normal operation;Users can adjust power-saving percentage (20%~80%), which achieves the best power efficiency. - User initialization is not required.LED display status: The LED provides users visible positioning status. LED β€œON” when power connected - and β€œBLINKING” when GR-213U got positioned.Water proof design for industry standard. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B004ECO5VA | | Are Batteries Included | Yes | | Brand | Holux | | Connectivity Technology | USB | | Customer Reviews | 3.9 out of 5 stars 2 Reviews | | Display Type | LED | | Manufacturer | Holux | | Map Type | Satellite | | Map Types | Satellite | | Mfr Part Number | GR-213U | | Model Number | OD13GPS213 | ## Images ![Mini Smart Mouse Type GPS Receiver GR-213U by Koolertron - Image 1](https://m.media-amazon.com/images/I/31D+fOS2gjL.jpg) ![Mini Smart Mouse Type GPS Receiver GR-213U by Koolertron - Image 2](https://m.media-amazon.com/images/I/41DWlCHraeL.jpg) ![Mini Smart Mouse Type GPS Receiver GR-213U by Koolertron - Image 3](https://m.media-amazon.com/images/I/41QSHfOnqbL.jpg) ![Mini Smart Mouse Type GPS Receiver GR-213U by Koolertron - Image 4](https://m.media-amazon.com/images/I/41N85HoWXiL.jpg) ## Customer Reviews ### ⭐⭐⭐ Three Stars *by C***N on September 27, 2015* Did not come with software disk.
