From the U. S. Department of Energy’s Office of Electricity: On April 6, 2019, there will be an event affecting the electric transmission and distribution system that has industry concerned about the potential for a major disruption. During the Week Number rollover of the Global Positioning System (GPS), the week number that uses the 10-bit binary system … Read moreAre You Ready For The GPS Week Rollover?
On February 14, 1989, the first Global Positioning System (GPS) “Block II” satellite was launched into Earth’s orbit. To ensure global coverage, 23 additional satellites were launched over the following years at various altitudes and orbits. Thus, a new era of Land Surveying was born, although it would be several more years before it would … Read more30th Anniversary of First Block II GPS Satellite Launched Into Orbit

Back in January, 2016, Loyal Olson described a consulting project that required raising a state plane so that ground distances were very close to grid distances and state plane grid azimuths were preserved. The purpose of this post is to share the results of the research that Loyal? post prompted me to do. Let? explore the relationships and mathematics that make it possible to raise a Lambert state plane projection to provide ground distances and grid azimuths over a limited area.
The state of the cadastre in this country is still at an all time high at D+. Surveyors see the world of GIS as the next isolated individual parcel that will need to be surveyed, or resurveyed. That decision on which parcel and why that parcel needs surveying is always made by anyone but the surveyor.
Today, with survey grade GPS, measurements can be made to the nearest centimeters. Are today? advancements in technology improvements that we really need? Were the skills and accuracies of yesterday good enough for land measurements? Is GPS surveying just another way of challenging yesterdays’ skills?
Geodesy is the foundation of modern geospatial practice. In recognition of the importance of geodesy, the American Association for Geodetic Surveying (AAGS) is beginning to explore the idea of a Geodetic Certification Program. This effort is being led by the AAGS Geodetic Education and Certification Committee.
If you’ve been checking the January and February 2016 schedules for satellite launches, you might have noticed how busy it is. According to an article at Inside GNSS, there are several launches coming up over the next couple of months: Launch number five for the Indian Regional Navigation Satellite System (IRNSS) The twelfth and last … Read moreSpace Congestion FTW
You may remember the interference caused by LightSquared (see what I did there?) a few years ago when they tried to build a 4G network using satellites and cell towers. If you were living under a rock at the time, let’s just say that LightSquared wanted to do things that would have messed with our … Read moreLightSquared Is Back
Carlson Software has released the 2016 version of its SurveyGNSS data post-processing software. SurveyGNSS is a high-accuracy post-processing software for Land Surveyors and other related users. According to their website, Carlson has made a number of improvements as follows: More receiver raw data formats are supported. The list of supported formats for import is now: … Read moreCarlson Releases SurveyGNSS 2016
Update: The launch was delayed until that Saturday (October 31), but was successfully launched. It will commence operation upon completion of testing. The United States Air Force is set to launch the Atlas 5rocketinto orbit on Friday, October 30, 2015. The Atlas 5 will carry the GPS 2F-11navigation satellite into orbit and will ascendfrom Cape … Read moreGPS 2F-11 Scheduled to Launch on Friday
