The Cerulean GPS is rated to 300 meter depth and is designed to have a low non-snag profile and to ward off accidental blows. The LC86L is an ultra-compact GNSS module measuring 16.0mm × 16.0mm × 6.95mm with 26 tracking channels and 11 acquisition channels. It is designed to be compatible with Quectel’s GPS L80 module to provide a flexible and scalable platform for migrating from GPS to GNSS. The module has an integrated patch antenna and a high-performance GNSS chipset engine (AG3331 or MT3333) to support two GNSS constellations (either GPS + GLONASS or GPS + BeiDou). The LC86L combines advanced AGNSS (assisted GNSS), EASY™ (Embedded Assist System for self-generated orbit prediction), and LOCUS™ (internal logger) to achieve the highest performance.

Tracker 650 does only what you need a DVL to do, namely, to provide velocity information so that the vehicle control system can execute its advanced stabilization protocols like position hold and integrated position tracking. Rather than build in extra cost and complexity, Tracker 650 leverages the IMU in the vehicle as the central source of truth about attitude. This also simplifies setup as there is only one IMU to calibrate. Tracker 650 is perfect for integration by OEMs into their ROV platforms and Cerulean supplies all documentation and engineering support for these scenarios.
