Permanent Link to New NovAtel RTK GNSS Receiver Offers Advanced Heading Capabilities
NovAtel’s FlexPak6D enclosed GNSS receiver.
NovAtel Inc. has announced the FlexPak6D enclosed GNSS receiver, a flexible dual-antenna solution for application developers seeking a high-precision heading-capable positioning engine for space-constrained applications.
Designed for efficient and rapid integration, the compact, lightweight receiver tracks GPS, GLONASS, Galileo and BeiDou. Antenna placement is flexible, which means the antenna baseline can be set according to space available on the vehicle and the heading accuracy required. In addition, the modular nature of the FlexPak6D’s OEM6 firmware provides users with the ability to configure the receiver for their unique application needs.
Scalable for sub-meter to centimeter-level positioning, the FlexPak6D delivers NovAtel’s ALIGN precision heading and relative heading firmware, as well as its GLIDE firmware for smooth decimeter-level pass-to-pass accuracy, and RAIM for increased GNSS pseudorange integrity.
“Our FlexPak6D builds on our popular lightweight FlexPak form factor,” said Jason Hamilton, vice president of marketing for NovAtel. “The modular, flexible design makes it easy to integrate into land, air and marine-based industries, particularly for low payload UAV and robotic applications.”
The FlexPak6D will be available for shipping February 2, 2015.
