52 Show report | InterGeo 2018 discovered that building materials have specific physical qualities that allow them to be recognised automatically, although this camera requires larger drones because it weighs around 12 kg.” Quantum-Systems unveiled the updated version of its Trinity UAV, the Trinity F9. It is designed with a range of new technologies intended to improve accuracy, safety and facilitate the fixed- wing aircraft’s integration into civilian airspaces in accordance with current and future regulations. “In addition to anti-collision lights installed on the wings, body and tail, we’ve incorporated uAvionix’s PingUSB ADS-B In receiver into the qBase GCS to give operators live air traffic information. Although it wasn’t announced at the show, we can also integrate their Ping 20S transponder into the UAV for transmitting position, velocity and altitudes to other aircraft,” explained Florian Seibel. The Trinity also now comes with a dedicated PPK module with an antenna mounted in the tail section, as well as the Quantum iBase PPK base station to enable georeferencing of survey mapping data accurate down to 2-3 cm. “The anti-collision lights were spurred by a tender we have from India for 110 units, to fit with the new Indian UAS regulations, and the ADS-B has been added as we anticipate it becoming standard safety requirement for all VTOL- transition UASs,” Seibel said. The 2.4 m wingspan craft has an MTOW of 4.5 kg and a cruising speed of 61 kph. The qBase flight planning software uses Esri high-resolution digital elevation data to enable automatic generation of flight paths optimised for energy consumption and collision avoidance. Bormatec displayed its Corex UAV, its latest EPP-foam constructed fixed-wing unmanned aircraft. It has notable design differences from previous models. Franz Bormann told us, “The foam is durable and flexible enough for use in UAS airframe bodies, but after hard landings or landings on rocks, EPP bodies become too damaged. So we decided to develop a more durable airframe, especially for surveyors working in areas like construction who need an inexpensive foam UAS that can work in rough terrain.” The flying-wing shaped UAV therefore uses a cardboard-like plastic called Coroplast as a ‘sandwich’ around the middle of the body, which is built with a smooth outer finish and a honeycomb structure to provide the desired durability. The 1.1 m wingspan craft has an MTOW of 1.5 kg and a payload capacity of 300 g, with different versions featuring different camera systems. Geoscan Group unveiled its new Geoscan 201 Urban UAV, a blended-wing body aircraft intended for surveys in city airspaces. It uses two downward-facing Sony DSC- RX1 cameras (each tilted about 15° to the left and right to enable 3D modelling), with position data for navigation and georeferencing supplied by a dual- frequency antenna from Topcon, and post- processing with Agisoft PhotoScan (which is owned by Geoscan). “With two payloads, the batteries can power the craft for up to two-and-a-half hours,” said Lida Hsieh. “And the angle of the two payloads means you don’t have to make two flights to create a 3D map.” A single BLDC motor at the rear provides airspeeds of between 64 and 130 kph for up to 210 km before rolling and landing on its back, then releasing a parachute from its undercarriage. TinyMobileRobots displayed its TinySurveyor UGV, an 18 kg three- wheeled vehicle designed for urban operations on hard surfaces such as tarmac and concrete. “It can print lines and points for roads after the user has uploaded a layout plan in .DXF or .CSV format for operation December/January 2019 | Unmanned Systems Technology The Trinity F9 from Quantum-Systems comes with a dedicated PPK module Bormatec’s Corex uses a cardboard-like plastic called Coroplast
