Product Description

Model Name: GM268

GPS GLONASSDual System (Default) Concurrent GNSS Receiver, include QZSS+SBAS

G-Mouse: For Laptops PC Portable Mini GPS Receiver

Suport Windows and Linux OS

it support QZSS and SBAS signals that received concurrently with GPS&GLONASS signals.

What is QZSS?

Answer：The Quasi-Zenith Satellite System (QZSS) is a navigation satellite overlay system for the Pacific region covering Japan and Australia which transmits additional GPS L1C/A signals. when swith to GPS Protocol, it can receive and to track these signals simultaneously with GPS, resulting in better availability, especially under bad signal conditions e.g. in urban canyons. What is SBAS?Answer:SBAS (Satellite-Based Augmentation System),These systems supplement GPS data with additional regional or wide area GPS augmentation data. The system broadcasts augmentation data via satellite which can be used by GPS receivers to improve the resulting GPS precision. SBAS satellites can be used as additional satellites for ranging (navigation), further enhancing precision. GM267 support the following SBAS : WAAS, EGNOS and MSAS.

Performance

Default: 1Hz update concurrent reception of GPS and GLONASS incl. QZSS, SBAS

GPS:

designed to receive and track the L1C/A signals provided at 1575.42 MHz by the Global Positioning System (GPS).

GLONASS:

It can receive and process the GLONASS satellite system as an alternative to the US-based Global Positioning System (GPS).it is designed to receive and track the L1OF signals GLONASS provides at 1602 MHz + k * 562.5 kHz, where k is the satellite's frequency channel number (k = -7, ..., 5, 6) . BeiDou:It can receive and process the B1I signals broadcast at 1561.098 MHz from the BeiDou Navigation Satellite System.The ability to receive and track BeiDou signals in conjunction with another constellation results in higher coverage, improved reliability and better accuracy.Currently, BeiDou is not fully operational globally and has Chinese continental coverage only. Global coverage is scheduled for 2020. Galileo:It can receive and track the E1-B/C signals centered on the GPS L1 frequency band. GPS and Galileo signals can be processed concurrently together with either BeiDou or GLONASS signals, enhancing coverage, reliability and accuracy. The SAR return link message (RLM) parameters for both short and long versions are coded by the receiver and made available to users via UBX proprietary messages. Galileo has been been operated according to ICD release 1.3 (December 2016). Since the Galileo satellite system has only recently reached Initial Services (IS) and does not yet offer Full Operational Capability (FOC), changes to the Galileo signal specification (OS SIS ICD) ) theoretically possible. Galileo reception is disabled by default. Augmentation Systems : Satellite-Based Augmentation System (SBAS)It supports reception of SBAS broadcast signals.These systems supplement GNSS data with additional regional or wide area GPS augmentation data.The system broadcasts range correction and integrity information via satellite which can be used by GNSS receivers to improve their resulting precision.SBAS satellites can be The following SBAS types are supported: GAGAN, WAAS, EGNOS and MSAS. Augmentation Systems :QZSSThe Quasi-Zenith Satellite System (QZSS) is a regional navigation satellite system that transmits additional GPS L1 C/A signals for the Pacific region covering Japan and Australia.it is able to receive and track these signals concurrently with GPS signals, resulting in better availability especially under challenging signal conditions, e.g. in urban canyons. Augmentation Systems :IMESThe Japanese Indoor Messaging System (IMES) system is used for indoor position reporting using low-power transmitters which broadcast a GPS-like signal.It can be configured to receive and demodulate the signal to provide an indoor location estimate .*This service is authorized and available only in Japan.*IMES reception is disabled by default

Overview:

GM268 is concurrent GNSS receivers and can receive and track multiple GNSS systems ( GPS, GLONASS, SBASand QZSS signals). two signals (GPS L1C/A GLONASS L1OF ) can be received and processed concurrently. QZSS and SBAS share the same frequency band as GPS and can always be processed in conjunction with GPS.

It can support USB 2.0,Can't suppert USB 3.0, If USB 3.0 ,Pls add USB Hub.
