Mobile snow depth sensor uses Novelda's nanoscale impulse radar

OSLO, NORWAY: Flat Earth Inc. has developed the first mobile snow depth sensor based on the Novelda AS NVA6000 impulse-based radar chip. The SDS-715 provides a non-contact approach for determining snow depth on the go. Measurement range is 0.15 to 2.0 meters with an accuracy of approximately 3.5 cm, snow condition dependent.

This rugged, low-cost snow depth measurement system is designed for snow grooming operations at Alpine and Nordic ski resorts. Snow depth beneath the snowcat is measured every second, approximately every 3 meters at 8 kph. The SDS-715 is cheaper than current ground penetrating radar systems on the market today. When used with Flat Earth's CatWorks snowcat navigation and information system, depth maps of the resort trails can be created and viewed in Google Earth.

"The Novelda NVA6000 Impulse Radar transceiver is a cutting-edge radar transceiver that incorporates extremely high frame rate and accuracy, in addition to unique penetration capabilities," remarks Flat Earth CEO Doug Roberts "Integrated on a single chip, this radar transceiver transmits pulses of high bandwidth."

In comparison to traditional technology, the Novelda NVA6000 Impulse Radar transceiver offers several improvements and value-added features. It effectively uses even extremely short microwave pulses, which makes it ideal for high-resolution ranging.
