15-mm GNSS global positioning module supports all satellites, concurrent operation

April 20, 2015 // By Graham Prophet
u-blox’ CAM-M8C is a low profile GNSS positioning module with an integrated wideband chip antenna for reception across the entire L1 band. The 9.6 x 14.0 x 1.95 mm module has -167 dBm sensitivity, built-in antenna for ease of integration, and low power consumption.

The module offers simultaneous GNSS operation for GPS/GLONASS, GPS/BeiDou, or GLONASS/BeiDou to deliver accurate, jamming-resistant and reliable positioning anywhere in the world. With high sensitivity, the CAM-M8C integrates a u-blox M8 satellite receiver, crystal oscillator, SAW filter and low-noise amplifier. It also has an input for an external active antenna and when using this option the internal antenna acts as a backup. Novel antenna design allows the module to maintain its performance regardless of physical orientation. This makes the product suitable for mobile applications with frequent change of bearing.

Kim Kaisti, Product Manager, Product Center Positioning, commented, “Where space is at a premium, for example in emergency call systems, in handheld navigation or in wearable devices, the CAM-M8C module offers a very cost-effective way to bring products to market quickly due to its small size and high levels of integration. It does this without compromising performance or reliability, and leaves system designers free to concentrate on other important aspects of their product development.”

The CAM-M8C is footprint compatible with u-blox UC530 and UC530M modules, providing an easy upgrade path. An evaluation kit, the EVK-M8CCAM, offers a quick way to become familiar with the CAM-M8C module and assess its performance in specific applications.

The u-blox M8 GNSS receiver antenna module is delivered in u-blox Professional Grade and is qualified to JEDS47 and ISO16750 standard: “Road vehicles – Environmental conditions and testing for electrical and electronic equipment”. The product is manufactured in ISO/TS 16949 automotive-certified production sites.
