Introduction to Synthetic-aperture Radar (SAR)

Introduction to Synthetic-aperture Radar (SAR)

February 24, 2021

Applications of SAR include topography, oceanography, glaciology, geology (for example, terrain discrimination and subsurface imaging), and forestry, including forest height, biomass, deforestation ... the list is long.

But before you can do all that you need to know what SAR is and how it works.

Building a 4D “Digital Twin” of the Planet

Building a 4D “Digital Twin” of the Planet

February 11, 2021

Building a 4D Volumetric "Digital Twin" of the Planet using voxels. If you are unfamiliar with voxels, think of them as 3D pixels and in this case, each voxel can exist in an infinite number of time states which gives them a fourth dimension.

Navigating The Past, Present And Future Of GNSS

Navigating The Past, Present And Future Of GNSS

January 28, 2021

Previously, with only one constellation and GPS, you could see perhaps two or three satellites and quickly lose the positioning within the city. This is now rare to see in devices that do not support multi constellations. Plus, all the constellations are built to be compatible with each other — all the receivers that can see multiple constellations can compute the position using the different satellites

Mapping The Ocean Floor

Mapping The Ocean Floor

January 21, 2021

Knowing the depth and shape of the seafloor (bathymetry) is fundamental for understanding ocean circulation, tides, tsunami forecasting, fishing resources, sediment transport, environmental change, underwater geo-hazards, infrastructure construction and maintenance, and much more.

Despite many years of effort, less than 20 percent of the world ocean's seafloor has been mapped.

Satellite-based Augmentation System - A base station in the sky

Satellite-based Augmentation System - A base station in the sky

December 16, 2020

Satellite-based Augmentation System or SBAS  can augment standalone Global Navigation Satellite Systems such as GPS in a number of areas including accuracy, integrity, and availability.

It works by collecting raw positioning data from Continuously Operating Reference Stations (CORS) in the region, computing error corrections and disseminating these corrections to users from a geostationary communications satellite via an uplink ground station.
