Grandmaster Clock
All-in-one time-and-frequency master time and clock server
Spectracom’s VelaSync time server and grandmaster clock.
When the VelaSync time server platform was introduced in 2014, it met the needs of financial trading networks’ move to 10 gigabit-per-second networking. Now available with 40-GbE network interfaces, it offers high-performance synchronization for time-sensitive networks. Matching network speeds between timing and data on a single low-latency high-throughput network enhances synchronization accuracy and eliminates queuing delays and hidden time errors caused by slower connections. The availability of a network timing appliance with 40-GbE interfaces benefits any deployment of critical network infrastructure at high data rates.

SURVEY & MAPPING
USV Echo Sounder
Single-beam system for shallow water surveys
The CEESCOPE-USV is a waterproof one-box echo sounder, GNSS and broadband radio telemetry package that can be installed on practically any remotely operated unmanned surface vehicle (USV). The self-contained unit requires no interface with the USV, eliminating challenges of instrument data integration on the vehicle. Using real-time broadband radio telemetry, detailed 20-Hz dual-frequency soundings, up to 20-Hz RTK GNSS and a 3200-sample-per-ping digital echogram are available to the USV operator on shore via the CEE-LINK radio base station. Data from the CEESCOPE-USV telemetry link allows the operator to steer the USV along the survey line like in any manned boat survey. The CEESCOPE-USV offers users a range to their vehicle of more than 1,000 meters.

Airborne Sensor
Expanded functionality
The new ALS80-UP airborne sensor enables even more flexible data acquisition with extended range measurement capability. It takes advantage of the dual-output optical system pioneered in the ALS70 and enhanced in the originl ALS80. The AL80-UP has higher Multiple Pulse in Air (MPiA) operation settings, enabling data collection in extreme terrains with minimal variation in swath width due to terrain elevation variations. The ALS80-UP works perfectly in a wide variety of scenarios, including wide-area mapping, detail mapping from high-flying heights and detail mapping over mountainous terrain. With its expanded maximum range, the system has demonstrated good results at up to 6,000 meters above terrain and with terrain relief of up to 2,300 meters.

UAV
Imaging Camera
Thermal and radiometric functionality
The FLIR Vue Pro R adds radiometric functionality to the Vue Pro camera, giving drone operators the ability to save pictures for post-flight image analysis and accurately measure the temperatures of individual image pixels. Calibrated radiometric imaging allows it to capture the temperature data of every pixel in an image. When saved in Radiometric JPEG format, still images can be imported into FLIR Tools software for detailed analysis and reporting. FLIR Tools, a free download on FLIR.com, lets drone operators adjust settings including object emissivity, background temperature, target distance, relative humidity and thermal sensitivity, as well as assigning various color palettes for each image. The Vue Pro R records digital thermal video, along with radiometric thermal still images, to an on-board micro-SD card. For applications such as electrical inspection, infrastructure assessment and precision mapping, the onboard recording allows operators to capture high-quality thermal data for post processing and analysis.
