The paper describes a method for improving the coordinates of hydrological stations using the GNSS. Traditional methods of determining the coordinates of level posts are analyzed in this work. The requirements for the accuracy and installation of geodetic points of level posts are given. A scheme of the GNSS network of the coastal zone…

As the Covid-19 virus keep surging again and again,
The world rushes to get vaccinated.
And some saw and see opportunities in many ways,
There are many, who contributed to the crisis,
There are few who rival for credits and occupying market share.

Though the debate is understandable …

As Christopher Alexander conceived and defined through his life’s work – The Nature of Order – wholeness is a recursive structure that recurs in space and matter and is reflected in human minds and cognition. Based on the definition of wholeness, a mathematical model of wholeness, together with its topological representation…

Another feat of human perseverance
When the Mars 2020 Perseverance Rover
Landed on the surface of Mars on Feb 18,2021
To look for habitability, seek biosignatures, cashing samples and
test oxygen production from the Martian atmosphere.
Equipped with new entry, descent, and landing (EDL) technologies, such as Terrain-Relative Navigation (TRN),
That allows the rover to …

Free Resources to Protect Critical Infrastructure From GPS Spoofing
The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) has published the Positioning, Navigation, and Timing (PNT) Integrity Library and Epsilon Algorithm Suite to protect against Global Navigation Satellite System (GNSS) spoofing, or deceiving a Global Positioning System (GPS) device through false signals. These …
