NASADEM: Creating a New NASA Digital Elevation Model and Associated Products
By Lurker,
Our objective is to provide the scientific and civil communities with a state-of-the-art global digital elevation model (DEM) derived from a combination of Shuttle Radar Topography Mission (SRTM) processing improvements, elevation control, void-filling and merging with data unavailable at the time of the original SRTM production:
NASA SRTM DEMs created with processing improvements at full resolution

Veripos release LD900 quad-band GNSS receiver for marine
By Lurker,
Veripos has released the LD900, a quad-band GNSS receiver capable of tracking GPS, GLONASS, BeiDou, Galileo and QZSS constellations to provide reliable and accurate positioning. Access to multiple GNSS signals allow for better satellite availability and reduce the impact of satellite masking or blockage, which can affect positioning.
LD900 also receives L-band signals on multiple channels, providing access to the worldwide independent correction links and services provided by Veripos. With
Rocket Lab acquires Sinclair Interplanetary
By Lurker,
The US firm and its New Zealand subsidiary is the maker of the Electron launch vehicle and Photon line of primarily Low Earth Orbit satellites, which the acquisition of Sinclair’s capabilities will significantly bolster.
The move appears to be a major plank in Rocket Lab’s strategy to provide end-to-end launch and small satellite services, according to Peter Beck, Rocket Lab founder and CEO.
“When we talk to small satellite operators across the board their challenges are clear: They ne
New UAVOS parachute system for UAS
By Lurker,
UAVOS has successfully tested its new two-stage parachute system. The new parachute system provides slow descent of a UAS at high speed. It includes two parachutes — the pilot chute and a main chute used to slow and stabilize the UAS.
The decrease in the load speed on the UAS occurs due to the main chute opening delay function, when the pilot chute opens first. The parachute system is designed for UAS with speeds of up to 280 mph (450 kph) and weight of up to 110 lb (50 kg).

SPH Engineering announces bathymetric drone solution
By Lurker,
SPH Engineering has launched a new product to make bathymetric surveys of inland and coastal water.
The system — an unmanned aerial vehicle (UAV) integrated with an echo sounder — is time- and cost-efficient. It is suitable for mapping, measuring and inspecting tasks as well as environmental monitoring.
The system allows field workers to collect data with high accuracy quickly. It is easily transported, quickly deployed and twice as cost-efficient as traditional methods.
The UAV/e
