Permanent Link to OriginGPS multi-constellation module ready for IoT
OriginGPS, maker of small-format GNSS modules and cellular internet of things (IoT) systems, presented new products with customized IoT and GPS demonstrations at Embedded World 2019, Nuremberg, Germany, Feb. 26-28, Hall 3, Booth 3-121.
OriginIoT systems enable developers to rapidly develop IoT products with stackable add-ons, while all data is configured from the cloud, and no additional embedded code or RF knowledge is required.
OriginGPS’ latest release is the multi-constellation ORG1518-MK06 module. It combines low power modes for extended battery life, 8MB built-in Flash memory, AGPS support for extended ephemeris improving position calculation, and UART+I2C or UART+SPI interfaces.

An ultra-sensitive integrated patch antenna easily switches over to an external antenna via an integrated RF switch.
The ORG1518-MK06 is suitable for solutions requiring multiple antenna options, such as automotive aftermarket and agriculture applications.
Addressing the global IoT market with fast data transmission, the OriginIoT NB-IoT/CAT M with 2G fallback will be suited to devices that are battery-powered and transmit data only occasionally, such as parking and agriculture applications, resulting in a very long sensor battery life, typically 10+ years. The new model will be released later this year.
“The new products are based on OriginGPS patented technologies and retain the miniature footprint for which the company has become synonymous,” said Robert van Tilburg, vice president, Global Sales and Business Development, OriginGPS. “We are excited to offer our customers additional features and options to choose from, enabling them to reduce overall solution costs. 2019 is going to be an exciting year with technology advancements facilitating our product offering with more personalized IoT and GNSS products.”
OriginGPS partner Gemalto will also be presenting OriginIoT demos at Hall 3, Booth 3-438. Gemalto’s Cinterion LTE-M module is integrated in the OriginIoT systems to provide 2G, 3G, Cat1, Cat-M and NB-IoT cellular communication.
