Satellite insurance is a specialized branch of aviation insurance in which, as of 2000, about 20 insurers worldwide participate directly. [1] Others participate through reinsurance contracts with direct providers. [ 1 ]
GNSS systems that provide enhanced accuracy and integrity monitoring usable for civil navigation are classified as follows: [5] GNSS-1 is the first generation system and is the combination of existing satellite navigation systems (GPS and GLONASS), with Satellite Based Augmentation Systems (SBAS) or Ground Based Augmentation Systems (GBAS).

In Singapore, the Electronic Road Pricing (ERP) system will be switching to a GNSS-based system after the installation of the Onboard Units (OBUs) is completed in 2025. [10] Singapore's Land Transport Authority announced that the distance-based charging policy will not be implemented soon, with no concrete date on when the new policy will take ...
A surge in nonrenewals. Insurers using drones or satellite images as part of the underwriting process isn’t new. Where once companies sent agents into the field to take photos, “the use of ...
The World Teleport Association publishes lists of companies based on revenues from all customized communications sources and includes operators of teleports and satellite fleets. In order from largest to smallest, the Global Top 20 of 2021 were: [1] [2] SES (Luxembourg) Intelsat S.A. (Luxembourg) EchoStar Satellite Services (USA) Hughes Network ...
A "GNSS compass" uses a pair of antennas separated by about 50 cm to detect the phase difference in the carrier signal from a particular GNSS satellite. [8] Given the positions of the satellite, the position of the antenna, and the phase difference, the orientation of the two antennas can be computed.
A choke ring antenna is a directional antenna designed for reception of GNSS signals from satellites. It consists of a number of concentric conductive cylinders around a central antenna. The first choke ring antennas were invented at JPL; [2] since 1989 they have been improved and extended by many companies. [citation needed]
