ANELLO Photonics’ Optical Gyroscope & GNSS/INS Evaluation Kit presents design engineers with a full-featured environment for testing ANELLO’s SiPhOG (Silicon Photonics Optical Gyroscope) technology and comparing/combining its performance with MEMS IMUs (Inertial Measurement Units) and GNSS technology for inertial navigation and localisation tasks typical of applications including mapping and surveying, robotics, trucking, autonomous vehicles and ADAS, agriculture, mining, aerospace, and defence.
The key innovation with ANELLO’s solution is the size and cost reduction when compared to traditional optical gyroscope technology, which is typically reserved for aerospace and defence applications. Here, the high performance of optical gyroscope technology is required for accurate navigation when GNSS signals are not always available or can be jammed.
ANELLO’s SiPhOG takes this technology and shrinks it into a previously unseen form factor that enables its use in smaller end products and markets while retaining the superior temperature, shock, and vibration stability that makes currently existing compact technologies not viable for long-range inertial navigation. ANELLO’s EVK is able to maintain centimetre-level localisation accuracy over long journeys without the requirement for GNSS connectivity, at far lower cost than reference-grade localisation systems.
The EVK comes in a form factor of 106.7 x 38.1 x 127 mm, weighing just 0.454 kg, and includes everything you need to get started, including antennas for the dual 184-channel five-constellation (GPS, Glonass, Galileo, Beidou, QZSS) dual-band GNSS receivers. With an operating temperature of -40°C to +85°C and vibration and shock survival rated at 5 g and 40 g respectively, this unit can be mounted onto existing industrial-grade machinery for testing with ethernet, CAN, and USB/serial connection interfaces. The input voltage is 8-30 VDC with a typical power consumption of 4 W.
The key performance characteristics of ANELLO’s SiPhOG technology within the EVK environment are as follows:
- Data rate up to 200 Hz (position, velocity, altitude)
- Unaided heading drift: <0.5°/Hr
- GNSS Standard Positioning Service (SPS) accuracy: 1.2 m (0.02 m with RTK)
- <1.0 m drift for 60 seconds of GNSS outage
- Optical gyroscope (heading/z-Axis) bias instability: <0.5°/hr (3.0°/hr for 6-axis MEMS IMU)
- Optical gyroscope angle random walk: < 0.05°/√hr (0.3°/√hr for 6-axis MEMS IMU)
