NavSpark-BD model has GPS/Beidou receiver onboard, enabling users to use the latest GPS/Beidou navigation technology just as large smartphone makers are beginning to adopt this new technology. The NavSpark-GL model has GPS/GLONASS receiver onboard, enabling users to use dual-satellite navigation technology, GPS/GLONASS as used in high-end smartphones, in their hardware projects. The NavSpark development board makes the latest global navigation satellite technology easily accessible.
SkyTraq’s 7mm x 7mm QFN56 Venus822 quad-mode GPS/GNSS processor with extended I/O pins is used on NavSpark. Venus822 is designed to simultaneously process 34 GPS / GLONASS / Beidou / Galileo / QZSS / SBAS signals in parallel, thus having much higher computation power and larger memory than conventional 8bit or 32bit microcontrollers. Without using GPS/GNSS function, all the 100MIPS RISC/FPU processing power and 1MByte Flash + 212Kbyte RAM memory capacity is available for user application. When just using GPS-only mode or GPS/GLONASS, GPS/Beidou dual-satellite navigation mode, the remaining MIPS and memory still far exceeds what’s available on similar small, low-cost development boards on the market.
With average price of different model variants plus active antenna in range of $15 ~ $20, NavSpark’s goal is to provide the makers an alternative powerful, small development board with location-sensing capability, and at the same time making latest GPS/Beidou or GPS/GLONASS dual-satellite navigation technology as easily accessible as GPS to the users worldwide.
NavSpark is low-cost enough to leave in small hardware projects. For higher volume projects such as asset tracker, GPS fitness product, sports performance logger, toy quad-copter autopilot …etc., after rapid prototyping using NavSpark, volume usage can later change to lower cost 10mm x 10mm x 1.3mm Venus838FLPx module, a miniaturized LGA version of NavSpark. For applications benefiting from NavSpark’s high processing power and large memory without using GPS/GNSS, volume usage can later change to Venus822 chip to reduce cost.
