Topcon California GPS Network

Topcon California has developed one of the largest RTK networks in United States.   Presently there are 17 reference stations covering over 29,000 square miles in Central and Northern California.  All of the reference stations are GPS+ (GPS + Glonass) dual frequency receivers.  The original 7 reference stations surrounding the Sacramento metro area have been in operation for approximately 20 months.  During the last 9 months, Topcon California has more than doubled the number of reference stations expanding coverage from as far north as Willows down to as far south as Los Banos.  And, there is more to come.  We are continuing to expand the network in all directions. Our network is also the only network developed to support both survey and machine control applications.

We make available a number of subscription plans depending on your needs.  We even offer a daily and weekly rate for those short term projects.  We offer a month to month annual subscription as well as a discounted 1 year single payment subscription plan.

Purchase your GPS rovers from us and we have some very special Network options for you to choose from.  Our network will be used to add value to your GPS rover purchase in several different ways.

• Reduced initial outlay (elimination of the cost of the base station)
• Decreased security risk
• Dramatically increased range capabilities
• Elimination of radio problems
• Time saved not having to setup a base station
