Marianas GPS, LLC

A Guam Based Electronic Engineering Firm. We create things that don't exist yet.

We create Digital Topographic and Navigational Maps for our Islands and Oceans.


We created the first Garmin compatible digital maps of the Island well before it was fashionable, with Garmin's blessing. Since then we have created maps for Both the CNMI and the Republic of Palau and continue to update our current maps monthly. With thousands of points of interest that continually grow and change, MGPS maps continue to be the most accurate of any map available.

We are also working with local fisherman and other sea-going entities to create Blue Charts for the oceans around Guam, the CNMI, and the Republic of Palau. While creating an excellent product we aim to increase safety and convenience to our residents and visitors by ensuring the most accurate and up-to-date data available is at their fingertips.

We create Mobile Applications for Android and iOS.

We create cool things for the Internet Of Things


The Internet Of Things is poised to take over the world, and Marianas GPS is ready. We don't like re-inventing the wheel; If we can find a device you need, we're going to use it. But sometimes there isn't anything available yet. Using Arduino controllers integrated with low cost sensors and communications components, we can create a device that you can control from across the room, or across the globe. Whether it's automating your home, automating an industrial complex, Marianas GPS has the technical ability to integrate existing technology with custom solutions to satisfy your needs.


We create things in 3D


When we create custom electronic devices for the Internet Of Things, we have to house them in waterproof boxes to survive the harsh Tropical environment. We thought about just purchasing and modifying off the shelf enclosures. but every project is different. So we decided to invest in 3-D printing to allow for us to create the absolute best enclosure for the task. And while it's idle, you're welcome to rent time on the machine. Buy us a spool of filament and let's talk.

We create custom Software


Sometimes, you need software that isn't available. Whether based on a PC or a Macintosh, MGPS has you covered. Rapid Application Development for Windows or Macintosh is firmly in our wheelhouse. We have been developing for the Macintosh since 1986, for the PC since 1992. When you need a software solution to resolve repetitive task workflow, MGPS is the only direction you need to go.



We create movies with our drone

Until we get our commercial drone pilot's license, we're not setup to accept commercial ventures with our drone yet. At least, not within the United States. But we enjoy flying our waterproof drone in and around our islands. We can land and take off from the water if the seas are not too rough, and the view from underwater and from the air is spectacular! We look forward to getting our certifications in order soon. Stay tuned!
