The transmit antenna is a key element in the DGPS service provision. The antenna efficiency directly impacts upon the amount of power transmitted and the corresponding signal coverage. To make optimal use of the stations they should provide coverage that is available to the usable limit of the broadcast. In other words, the user should switch stations not because a signal is weak but because it is beyond the recommended usable range limit. Infrastructure Other support infrastructure includes the power system, security system and any required communication systems.
Many systems come with a one year maintenance agreement.
ICAN s experience has shown that this may not be sufficient to address the needs of a complex system like a DGPS Station. ICAN would make recommendations to the client regarding this issue so that clients make the best use of their resources. The decision to perform maintenance in-house or through a contract can be complex and difficult to make. It has to be based on cost and other, possibly more important, issues such as security and the development of expertise in-house. Training Training is crucial to an organization that wants to make the best use of their resources.
