 9101S4 |
GPS Engine Board |
|
| |
 |
|
The 9101S4 GPS module is a high sensitivity, low power, Surface Mount Device (SMD)
that fully utilized SiRFstarIV upgraded features.
This 48-channel Global Positioning System (GPS)
receiver is designed for a wide range of OEM applications and is based on the GPS signal search
capabilities of the SiRFstarIV GSD4e ROM chipset, SiRF’s newest chipset technology.
The 9101S4
provides flexible bus interfaces (Optional : UART, I2C or SPI reserved for customizing special user
applications ). |

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 -163dBm, even without network assistance.
(SiRF StarIII has only -159dBm sensitivity)
- Support SiRFaware technology :
- Support adaptive “Micro Power Controller” power management mode.
- Only 8mW 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
