Claimed to be the world’s smallest GPS module, the NanoSpider from OriginGPS is now being made avauilable in Europe by distributor Acal BFi. The NanoSpider is a fully integrated, highly sensitive GPS receiver module. Measuring 4.1 x 4.1 x 2.1mm and with minimal power consumption, it is ideal for smart watches, wearable devices, trackers, and digital cameras.

A double-sided circuit design reduces footprint size and makes the Nano Spider 47 percent smaller than previous solutions.

Offering accuracy of approximately one metre, the Nano Spider achieves a rapid time to first fix (TTFF) of less than one second, and tracking sensitivity of -163dBm.

The module achieves a state of near continuous availability by detecting changes in context, temperature and satellite signals.

By maintaining and opportunistically updating its internal fine time, frequency, and satellite data, the Nano Spider consumes mere microwatts of battery power.

The module also features OriginGPS’ proprietary Noise Free Zone (NFZ) system. Increasing noise immunity even under marginal signal conditions, it allows the module to provide high accuracy in dense urban areas, under thick foliage, or when the receiver rapidly changes position.
