About Datum Systems

Datum Systems is a small, but highly respected company in the heart of Silicon Valley that designs and manufactures innovative satellite communications ground equipment for SCPC, MCPC and VSAT point-to-point or point-to multipoint networks. We specialize in reliable high performance satellite modems for a variety of Government and Commercial applications, including IP data, VOIP, cellular backhaul, banking, distance learning, disaster recovery and business-to-business enterprise.

Datum Systems:

Datum Systems Inc. is a wholly privately owned company that has been in business since 1986, and incorporated since 1995. Originally, Datum Systems designed modems and various communications gear as an OEM supplier for other companies. Many of our first modems were shipped with someone else’s name on it. In 1996, however, Datum Systems began manufacturing satellite modems under its own Datum Systems brand name. Today over 80% of the equipment shipped carries the Datum Systems logo.

We have a lot of pride in our name and our reputation. Our goal is to design and manufacture the highest performing and most reliable equipment that you can buy for the money.

Our Product Design Philosophy

We manufacture the highest quality and most reliable modem in the industry by concentrating solely on satellite modems. Our modem products are rigorously designed to provide the absolute best performance at the lowest cost. Datum Systems equipment is also engineered to be built extremely efficient. Testing is virtually all automated, from initial checkout, through

The electronic design features zero adjustments, and comprehensive digital processing. Extensive use of Digital Signal Processing and FPGA’s keep the complexity hidden inside high reliability chips. Our hallmark is our direct modulation and demodulation, which gives us superior performance with fewer parts and higher integration. We directly modulate and demodulate at 70 MHz, 140 MHz and also at L-Band. Most of the signal processing is accomplished in Field Programmable Gate Arrays or FPGA’s. The design of these incorporates communications and logic processes written in high level hardware design language.

We invite you to compare our modem design and performance to any competing product. Many of our customers have performed extensive comparative testing and found that our modems significantly outperform any other modem on the market. This means that your satellite maximum power/bandwidth efficiency spectrum cost is lower using our equipment than any other modem.

Our Sales Model

Datum Systems has no direct sales force or field offices. It uses distributors, resellers and system integrators to interface and provide sales support to prospective buyers. What this means to you is lower pricing. Because our distributors buy and stock large volumes of our modems, they are able to pass these savings directly on to you. Our distributors and resellers promote and sell our modems in many diverse geographic regions and markets. We have large and small companies in Asia, South America, Australia, Africa and Russia who are selling our products within their “Home” markets. At the same time, we help “System Designers” by making certain that our products meet their requirements and sometimes-unique needs through direct communication.

Our Logo

In case anyone is curious about our name or logo, here is the straight story. When we first started Datum Systems we needed a name and logo. After weeks of searching names that we generated on a computer, Dave Bagby came up with the name “Datum”, which refers to the reference or reference line from which other measurements are made. We liked it, so I started making a logo on an old Macintosh computer. It is meant to represent a two-dimensional reference mark. The rest is history.
