When it comes to GPS chips, Broadcom isn't the first company we think of, but its latest addition to its growing family of GPS chips – or GNSS receivers as they are starting to become known as with additional navigation systems launching – offers indoor navigation with the help of "other wireless technologies".

When it comes to GPS chips, Broadcom isn't the first company we think of, but its latest addition to its growing family of GPS chips – or GNSS receivers as they are starting to become known as with additional navigation systems launching – offers indoor navigation with the help of "other wireless technologies".

Some of these other wireless technologies are Wi-Fi and Bluetooth 4.0 low-energy beacons (where available), sensors and NFC technology to help with indoor navigation in say a shopping centre for example.  The BCM4725 as the new chip is known as also incorporates support for satellite-based augmentation system or SBAS which allows for ground stations to further enhance the navigation abilities of the device containing the new Broadcom controller.

Also integrated in the BCM4725 is support for the GPS and GLONASS satellite navigation systems as well as support for QZSS or Quasi-Zenith Satellite Systems which for example Japan will be using to further improve navigation accuracy.

Broadcom claims that the BCM4725 is 50 percent more power efficient than its previous generations of GPS chips and that it thanks to the 40nm manufacturing process it will also take up 44 percent less PCB space inside devices. Broadcom has also integrated more features, such as a low noise amplifier to reduce the BOM cost for the device makers. The BCM4725 is available as of right now and Broadcom is currently shipping it to its partners, although it'll likely be quite a while before the first devices start to appear with the new chip.
