The Oregon Department of Transportation (ODOT) has expanded its use of DT Research GNSS rugged tablets to all 15 of its construction management offices across the state, and also use the tablets for biology, geology, roadway and wetland projects.

DT Research worked closely with ODOT to design purpose-built rugged tablets that empower state workers to easily collect and transmit geospatial measurements in the field using GNSS real-time kinematic (RTK) technologies.

“DT Research’s GNSS rugged tablets have enabled us to bring high-accuracy geospatial measurements to workers across the Department of Transportation, which has literally changed the way we work,” said Chris Pucci, construction automation surveyor at ODOT. “The tablets have enabled us to save time, reduce costs and improve the accuracy of projects through ‘digital-as constructed’ measurements and real time data capture.”

The tablets have a dual-frequency GNSS module built in, which provides stand-alone sub-meter accuracy to centimeter-level accuracy with RTK from GPS, GLONASS and Galileo satellites.

The tablets are compatible with existing survey and GIS software for mapping applications and provide an advanced workflow for data capture, accurate positioning and data transmitting.

“We now have essentially created one-person survey crews because the DT Research tablets are so much easier to use than a tape measure and paper to accurately calculate and record measurements during complex construction projects,” Pucci said. “Using the tablets saves us an average of $2,000 for every survey-grade measurement job that does not require a full survey crew.”

“In addition, the tablets have provided us with a contract verification system by having highly accurate digital-as-constructed measurements that are delivered immediately and stored forever, which saves the state time and money by avoiding independent re-measurement checks due to billing discrepancies at the end of a project,” added Pucci.

The DT Research GNSS tablets can store up to 1 Terabyte of data for field data collecting. Users can avoid down time with a high-capacity hot-swappable battery pack, which delivers 60 or 90 watts for up to 15 hours of continuous mobile communications. The units include Long Range Class 1 Bluetooth, which powers wireless connectivity up to 1,000 feet and 4G mobile broadband.

“The simplicity of how the DT Research tablets work is amazing,” Pucci said. “Unlike complex professional survey equipment, the DT Research tablets are a Windows-based mobile device with a user interface that is familiar to workers. In just two hours, I can easily train state workers with diverse skill sets to measure quantity, linear features and volumes for a variety of projects — and they are ready to go.”

The tablets run on Microsoft Windows 7 Professional or Windows 10 IoT Enterprise and are high performance devices with an Intel 6th or 8th Generation Core i5 or i7 processor. The rugged tablet is designed for outdoor use with a brilliant LED-backlight, 800 nits sunlight-readable screen and capacitive touch.

“We have found the DT Research tablets to be incredibility easy to manage and highly durable — we just turn them on and they work,” said Pucci. “In the three years that we have used the tablets, we have had very few technical support questions and they hold up well in different weather conditions. There isn’t a comparable product on the market at the price point.”

The DT Research tablets are military-grade durable devices, yet lightweight, offering the versatility to be used in field-to-office settings. For use in harsh environments, the tablet is fully ruggedized to meet the highest durability standards with an IP65 rating, MIL-STD-810G for vibration and shock resistance and MIL-STD-461F for EMI and EMC tolerance.

For use in a variety of environments, the tablets are complemented by many accessories including: external antennas, pole mount cradles, detachable keyboards, battery charging kits and digital pens.
