Founded in 2015, SUBTEQ.IO designs a new generation of wireless GPS specifically for divers, featuring a touch tablet we manufacture.
The localization system we developed over a ten-year period is specifically designed to operate in shallow depths where the effects of acoustic multi-path are most pronounced.
Our differentiation is in the technology we use: our tablet is equipped with an FPGA processor. There are two advantages to implementing an FPGA processor in an underwater tablet.
1. An FPGA processor is programmable. Thus, software updates can improve both the navigator interface and add functionality at the acoustic signal processing level. At this point, we are capable of processing high-frequency acoustic signals through complex signal processing algorithms, notably to deal with the effect of these acoustic multi-paths in the 0-20 meter zone and near walls. We anticipate further developments that are currently in the research and development stage, such as moving from three to two buoys or operating close to boats and running engines.
2. Embedding this FPGA processor on a touch tablet allows interaction underwater and embedding algorithms in a fast development cycle. The screen allows real-time debugging underwater, and the touch interface allows the most complex algorithms to be implemented in an Agile approach. This agility makes it easier to identify areas for improvement, to develop solutions in line with users, and to debug our equipment as quickly as possible by informing users with intervention tickets.
Today, our development has led to a first version of a GPS for divers that we are commercializing in Beta version. An Agile approach will be applied with customer data retrieval to improve the user interface.
In addition, we offer technical services to help implement study models, intra-company trainers for Agile development of embedded systems, and we also intervene in engineering schools in the field of robotics.

Save time by joining a site and marking POIs in real-time
Prepare for your dive: by loading GeoTiff maps.
Deploy buoys: position the three buoys in a triangle around the dive site, within a maximum radius of 300 meters.
Navigation : while submerged, you can view your position, orientation using a digital compass, and the position of points of interest. You can then navigate towards them.
Place POIs on the map: in the workshop, it is possible to pre-register points of interest associated with your GeoTiff maps.
Add POIs: while submerged in real-time, you can mark POIs and enter additional custom parameters (marker type, width, height, color, etc.).
Export POIs: once back in the workshop, it is possible to retrieve a list of POIs with associated values in a CSV file and other formats (GPX, etc.).
WIFI network: a WIFI network allows you to connect to the touch tablet to load maps, load POIs and retrieve data at the end of the operation.
Bluetooth network: a Bluetooth network allows quick configuration of the tablet and GPS buoys on-site from a tablet or smartphone (check proper functioning, GPS point history, retrieve and clear the list of POIs, etc.).
Pelican case transport case: the durable transport cases allow the equipment to be transported with peace of mind.
Waterproof case: the transport cases are suitable for use in a maritime environment.
- A system includes an underwater GPS navigator and three GPS surface beacons
- The range is 300 meters around the beacons and up to 40 meters deep
- The precision is on the order of meters (depending on the GPS signal quality of the buoys)
- The autonomy of the buoys and the navigator is 4 hours
- The maps are loaded before the dive
- The number of simultaneous divers is not limited
- Maximum diver speed: 0.2 m/s
- Heading display
- Attention: Currently, the position information is not transmitted to the surface (developments are in progress)
