LR9151 GPS/GLONASS/Galileo SiRF V GPS Module

Features:

SiRF Star V ultra low power chipset

GPS, GLONASS, Galileo and SBAS reception for high GNSS availability and accuracy

Compact module size for easy integration : 15 x 14 x 2.8 mm

Fully utilized SS5 upgrade features


The LR9151 GPS module is a high sensitivity, low power, Surface Mount Device (SMD) that fully utilized SiRFstarV upgraded features. This 48-channel Global Positioning System (GPS) and Global Navigation Satellite System (GLONASS) receiver is designed for a wide range of OEM applications and is based on the GPS signal search capabilities of the SiRFstarV CSRG05e ROM chipset, Serf's newest chipset technology. The LR9151 provides flexible bus interfaces (UART).
The LR9151 is designed to allow quick and easy integration into GPS-related applications such as:

-Mobile gaming

-Cellular handsets

-Cameras

-Asset tracking

-Other location-aware consumer devices Premium on-chip software provides a new level of continuous location awareness by employing

-Opportunistic ephemeris decode and advanced power management, which enable the GPS receiver to stay in a hot-start condition nearly continuously while consuming very little power

-Full support for client-based and server-based SiRFInstantFixTM

-Dynamic contextual awareness, temperature monitoring, and MEMS sensors that work in concert to conserve power and boost performance

-Use of software control modules to achieve power saving state


SiRF V GPS Module Features

Performance

-Highest performance Solution:

-GPS, GLONASS, Galileo and SBAS reception for high GNSS availability and accuracy

-High sensitivity navigation engine (PVT) tracks as low as GPS:-164dBm、GLONASS:-161dBm

-48 track verification channels

-SBAS (WAAS or EGNOS,MSAS)

-Active Jammer Remover:

-Removes in-band jammers up to 80 dB-Hz

-Tracks up to 8 CW jammers

-Multimode A-GPS (Autonomous, MS-Based, and MS-Assisted)-Need operator support

-Embedded CGEE / SGEE (With back-end server support) speed up TTFF a lot and makes cold start time to be around 20+ seconds.

-SiRFGeoRecovTM Reverse EE makes positioning process being done under power
saving mode.

-Reacquisition Time: 0.1 second

-RF Metal Shield for best performance in noisy environments


Hardware and Software

-Based on the high performance features of the SiRF Star V low power single chipset.

-Adaptive Micropower Controller:

-Only 50 to 500μA maintains hot start capability

- <10mW required for TricklePower modeRoHS compliant (lead-free)

-SMT pads allow for fully automatic assembly processes equipment and reflow soldering

-Advanced Navigation Features:

-Smart sensor I2C interface

-Interrupt input for context change detection


Advantages

-Built-in LNA

-Built-in internal ROM and based on Firmware 4.1.X

-It can remove in-band jammer up to 80db-Hz and track up to 8CW jammers, so the module can prevent GPS signal interference when design-in the electrical device with noisy electrical signal interferences such as Laptop, mobile phone, DSC, etc.

-Maintain tracking sensitivity as low as GPS:-164dBm、GLONASS:-161dBm, even without network assistance. (SiRF StarIII has only -159dBm sensitivity)

-Support SiRFaware technology :

-Support adaptive “Micro Power Controller”power management mode.

 - <10mW Trickle Power, so user can leave power on all day instead of power off

-Suitable for battery drive devices that need lower power consumption application

-Ideal for high volume mass production(Taping reel package)

-Cost saving through elimination of RF and board to board digital connectors

-Flexible and cost effective hardware design for different application needs

-Embed CGEE (Client Generated Extended Ephemeris) that can capture ephemeris data from satellites locally and predicts ephemeris out to 3 days. So if the module was off within 3 days, it could complete positioning process with limited time just like hot start.
