I've got Intramaps Roam installed on a Panasonic Toughpad fz-g1 with integrated u-blox M8 gps.
When I open up GPSviewer I can see my position, everything seems fine. When I enable GPS with intra-maps roam, it says 'GPS Active' but the lat lon reading is 0,0.
I'm connected on COM3 with 9600bps.
Any ideas what's going wrong?
This has been patched in a newer (unreleased) version of Roam. You can build Roam from source if you want to try it out, or grab a build from here
It seems those GPS get the GLONASS messages as well as the normal GPS ones. The GPS module in QGIS didn't handle both of the messages. I have patch Roam to handle both.
Global Positioning System
The Global Positioning System (GPS), originally Navstar GPS,  is a satellite-based radionavigation system owned by the United States government and operated by the United States Space Force.  It is one of the global navigation satellite systems (GNSS) that provides geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites.  Obstacles such as mountains and buildings block the relatively weak GPS signals.
The GPS does not require the user to transmit any data, and it operates independently of any telephonic or internet reception, though these technologies can enhance the usefulness of the GPS positioning information. The GPS provides critical positioning capabilities to military, civil, and commercial users around the world. The United States government created the system, maintains it, and makes it freely accessible to anyone with a GPS receiver. 
The GPS project was started by the U.S. Department of Defense in 1973, with the first prototype spacecraft launched in 1978 and the full constellation of 24 satellites operational in 1993. Originally limited to use by the United States military, civilian use was allowed from the 1980s following an executive order from President Ronald Reagan after the Korean Air Lines Flight 007 incident.  Advances in technology and new demands on the existing system have now led to efforts to modernize the GPS and implement the next generation of GPS Block IIIA satellites and Next Generation Operational Control System (OCX).  Announcements from Vice President Al Gore and the Clinton Administration in 1998 initiated these changes, which were authorized by the U.S. Congress in 2000.
During the 1990s, GPS quality was degraded by the United States government in a program called "Selective Availability" this was discontinued on May 1, 2000 by a law signed by President Bill Clinton. 
The GPS service is provided by the United States government, which can selectively deny access to the system, as happened to the Indian military in 1999 during the Kargil War, or degrade the service at any time.  As a result, several countries have developed or are in the process of setting up other global or regional satellite navigation systems. The Russian Global Navigation Satellite System (GLONASS) was developed contemporaneously with GPS, but suffered from incomplete coverage of the globe until the mid-2000s.  GLONASS can be added to GPS devices, making more satellites available and enabling positions to be fixed more quickly and accurately, to within two meters (6.6 ft).  China's BeiDou Navigation Satellite System began global services in 2018, and finished its full deployment in 2020.  There are also the European Union Galileo positioning system, and India's NavIC. Japan's Quasi-Zenith Satellite System (QZSS) is a GPS satellite-based augmentation system to enhance GPS's accuracy in Asia-Oceania, with satellite navigation independent of GPS scheduled for 2023. 
When selective availability was lifted in 2000, GPS had about a five-meter (16 ft) accuracy. GPS receivers that use the L5 band can have much higher accuracy, pinpointing to within 30 centimeters (11.8 in).   As of May 2021 [update] , 16 GPS satellites are broadcasting L5 signals, and the signals are considered pre-operational, scheduled to reach 24 satellites by approximately 2027.
Worldwide pandemic situations drive countries into high healthcare costs and dangerous conditions. Hospital occupancy rates and medical expenses increase dramatically. Real-time remote health monitoring and surveillance systems with IoT assisted eHealth equipment play important roles in such pandemic situations. To prevent the spread of a pandemic is as crucial as treating the infected patients. The COVID-19 pandemic is the ongoing pandemic of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
We propose a surveillance system especially for coronavirus pandemic with IoT applications and an inter-WBAN geographic routing algorithm. In this study, coronavirus symptoms such as respiration rate, body temperature, blood pressure, oxygen saturation, heart rate can be monitored and the social distance with ‘mask-wearing status’ of persons can be displayed with proposed IoT software (Node-RED, InfluxDB, and Grafana).
The geographic routing algorithm is compared with AODV in outdoor areas according to delivery ratio, delay for priority node, packet loss ratio and bit error rate. The results obtained showed that the geographic routing algorithm is more successful for the proposed architecture.
The results show that the use of WBAN technology, geographic routing algorithm, and IoT applications helps to achieve a realistic and meaningful surveillance system with better statistical data.

Historical Maps at Your Fingertips
Earlier this month, the USGS launched “TopoView 2.1”, an enhancement to the current popular TopoView mapping service that lets users discover, interact, and download historical USGS topographic maps scans.
TopoView 2.1 is a modern web application built on an open source mapping platform that is free of charge. The highly interactive service provides tools and procedures that allow users to easily find historic map scans from USGS’s Historical Topographic Map Collection and even compare those with modern day maps.
The new version is full of improvements and advancements based on hundreds of user comments and suggestions. Upgraded features include:
- new user interface that’s faster and easier to use,
- access and download maps from a variety of search terms
- intuitive tools to compare historical maps with maps of the present.
- ability to preview maps within the interface
- filters and searches that work seamlessly with the map records table to get you the info you want with just a few clicks.
To further assist users with these features, the TopoView team has released a “how to” video to walk through the download and comparison process.
TopoView highlights one of the USGS's most important and useful products, the topographic map. In 1879, the USGS began to map the Nation's topography. This mapping was done at different levels of detail, in order to support various land use and other purposes. As the years passed, the USGS produced new map versions of each area.
The most current maps are available from The National Map and US Topo quadrangles. TopoView shows the many and varied older maps of each area, and so is useful for historical purposes—for example, the names of some natural and cultural features have changed over time, and the 'old' names can be found on these historical topographic maps.
TopoView was created by the National Geologic Map Database project, in support of topographic mapping program managed by the National Geospatial Program. Geologic mapping and topographic mapping at the USGS have a long tradition together.
