GPS Calendars

GPS or GNSS Calendars are different then traditional calendars that most of us are used to working with, yet they are pretty common these days due to the increased use of GPS equipment. Yet there is never one around when you need one, so if you find your self doing a lot of GPS field work like myself then you may notice that you will working in Julian Days & GPS Weeks frequently so will want to print off your own copy or use an online utility to help you out.

Now one can easily calculate this info but I find it quicker to just resort to reference pages or use online utilities and here a few that I use …

Precise Point Positioning GPS Processing

Sometimes when doing GPS field work I will often require a way to double check my own GPS Processing work or am sometimes too far from an active control network to tie into. Using Precise Point Positioning or PPP service in these situations has often come to my aid,  especially on jobs in Nunavut or in Northern Ontario.

The Canadian Geodetic Service provides a free online global GPS processing service called CSRS-PPP, where you can process files containing RINEX observations from either a single or dual frequency receiver in either static or kinematic modes. The service is free but does require that you sign up to obtain a username and password to gain access.

The Impact Of Modern GPS On Transportation & Society

GPS technology has been around a lot longer than most people give it credit for, and was meant more as a means of tracking satellites during the space race than for pin pointing our own positions on Earth. Now, not even a decade after the smartphone revolution took off and put GPS into the palms of our hands, GPS is taking on another new purpose …

Leica GS20 PDM GPS Sensor & GIS DataPro Processing Software

The Leica GS20 PDM (professional Data Mapper) handheld GPS unit was a small GPS device that was included with the RTK GPS unit that was purchased for my LIDAR research project at the AGRG in 2003. The GS20 did not come with very good user guides so we created a brief user guide …
