What is NTRIP?

Posted by Tyler on 2/7/2017 to Adopting Mobile GIS

This article breaks down the explanation of how RTK and NTRIP work to get field users centimeter level accuracy in real-time.

Galileo Satellite Constellation

Posted by AFS on 1/1/2017 to Knowledge Base

The Galileo system will have all brand new cutting-edge satellites technologically comparable to the U.S. GPS satellites and expectedly more reliable than the Russian Glonass satellites. But the best part is that the Galileo satellites will be able to add more available satellites to receivers capable of tracking more than two constellations simultaneously.

How Waterproof is that Unit?

Posted by Tyler on 12/6/2016 to Knowledge Base

One of the first couple questions users often ask about tablets, lasers, or GNSS receivers is how waterproof it is, especially those in the Pacific Northwest! This breaks down the different waterproof ratings.

RTK GPS Explained

Posted by Matt on 10/16/2016 to Knowledge Base

RTK GPS receivers are traditionally very expensive and their accuracy has been thought of as beyond the field mapping needs of most environmental and engineering firms, and government land management groups. However, with the introduction of Bluetooth RTK receivers for use with field tablets and mobile GIS, RTK’s potential has become less expensive to achieve and much desired. Add to that the availability of Bluetooth RTK receiver rentals from Anatum Field Solutions, and the continued progression of many companies into mobile GIS workflows with tablets becomes much easier and more affordable.

Mobile GIS: What to do with a GPS Antenna?

Posted by Matt on 3/17/2016 to Adopting Mobile GIS

One of the things professionals have to get used to when they switch from submeter handheld GNSS equipment to mobile GIS workflows with submeter GNSS receivers is their antenna. The important thing to keep in mind is the antenna needs to “see” as much sky as possible and preferably at all times. Below we present a few methods for working with the external antennas used with Bluetooth GPS and GNSS receivers.

Bluetooth GPS/GNSS For Mobile GIS Field Tested and Compared

Posted by Matt on 2/18/2016 to Adopting Mobile GIS

As an agnostic reseller and rental company of GPS equipment for use with Mobile GIS workflows, it is important that we know how the market performs. There are a multiple Bluetooth-capable GPS and GNSS receivers on the market now and we tested and compared them in real-world settings on our GPS Test Course. These field tests compared the accuracy and precision of Bluetooth submeter-rated GNSS receivers under conditions that ranged from open-sky to heavy canopy cover.

Using Tablets For Data Collection to Increase the Efficiency of Aerial Surveys

Posted by Matt on 1/18/2016 to Adopting Mobile GIS

Recent technological advancements in the form of tablets with mobile GIS software paired through Bluetooth with external GPS receivers are providing new opportunities to aerial surveyors that can substantially increase efficiency and accuracy while simultaneously reducing potential impacts to wildlife. GPS receivers that we have used include the Arrow 100 for submeter accuracy and the Bad Elf GPS Pro with 2.5-meter accuracy. The appropriate GPS receiver depends on your projects accuracy requirements.

Using Tablets in the Field: A Case Study

Posted by Matt on 1/18/2016 to Adopting Mobile GIS

Based on the results of our 2013 and 2014 case studies, we found the quality of data from using the mobile technology likely improved by eliminating potential errors introduced during the manual transfer of data from paper datasheets to an electronic database. The efficiencies gained in the documentation and distribution of the data resulted in substantial cost savings, even when considering some of the upfront costs of training and pre-survey preparation of automated data forms and creation of the Project specific GIS data in the mobile GIS app system. In addition, this technology is extremely adaptable and can be applied to survey data in a variety of disciplines aside from biology, including documentation of cultural resources surveys, geotechnical data, and other engineering data that may be needed for the Project.
