Machine types

Caterpillar has chosen AccuGrade as the brand name for all their machine control systems, -both 3D and conventional. Often a denominater is added to indicate the system configuration, such as AccuGrade GPS, AccuGrade ATS, AccuGrade Laser, etc.

The AccuGrade system is developed by Caterpillar Trimble Control Technologies LLC, a joint venture which also develops Trimble's GCS900 3D grade control system. Users of any one of these systems will be familiar with the other as the hardware and software are essentially the same.

Caterpillar's 3D grade control system incorporates, through their partnership with Trimble, technology from several other companies whose product portfolios Trimble has acquired through mergers and acquisitions. Among these are Spectra Physics Laserplane, Spectra Precision, Geodimeter and TDS.

The close relationship with Trimble has recently been strengthened by entering into another joint venture, -VirtualSite Solutions LLC, intended to provide solutions to manage worksite information and equipment fleets. Additionally, the two companies have embarked on creating a new distribution channel, SITECH, to distribute both Caterpillar and Trimble's construction technology products.

Many of the components of the AccuGrade grade control system can be interchanged between various machine types.

Caterpillar, Inc. is headquartered in Peoria, Illinois. It is a public company traded on NYSE under the symbol CAT.
