Dual frequency GNSS module enables sub-1m accuracy

OriginGPS has announced its first dual-frequency GNSS module, the ORG4600-B01, which will enable customers to build systems with sub-1m accuracy without implementing external components. by Jean-Pierre Joosting @ www.mwee.com

Measuring just 10- x 10-mm, the ORG4600-B01 module supports L1 + L5 GNSS reception with one RF port, enabling the use of a low-cost, dual-band antenna delivering sub-1m accuracy performance in real-world operating conditions. An alternate build option allows for separate L1/L5 RF outputs when dual antennas are required. The module is ideally suited for systems requiring ultra-accurate positioning, such as telematics, IoT and OBD applications.

OriginGPS collaborated with Broadcom to create a new miniature module with L1 + L5 support provided by the BCM47758 chip, enabling ultra-accurate GNSS positioning. The module was developed for solutions requiring super-precision GNSS and a dual frequency combination.

“This year has seen several satellites launched into orbit every month, most of them fitted with L5/E5 capabilities, and the Chinese and European Union governments plan to have their satellite constellations fully operational by 2020. Developing the ORG4600-B01 module with the BCM47758 GNSS receiver chip by Broadcom was the fastest and surest way to add a high quality dual frequency module to our portfolio and meet our customers’ increasing requirements for ultra-accurate GNSS modules,” said Haim Goldberger, CEO of OriginGPS.

“Size is a crucial parameter in GNSS dual frequency solutions,” said Prasan Pai, product marketing director for the Wireless Communications and Connectivity Division at Broadcom. “The collaboration with OriginGPS has created the industry’s smallest dual-frequency module with ‘no compromise’ quality. The collaboration enables Broadcom to reach new markets, such as precision agriculture, security, children tracking and fleet management.”
