* Garmin: They were a leader in handheld GPS devices, popular for outdoor recreation and navigation.
* Magellan: They were also a significant player in handheld GPS devices, competing directly with Garmin.
* Trimble: They focused more on professional-grade GPS receivers and software for surveying, mapping, and other applications.
* SiRF Technology: They were a major supplier of GPS chips used in a wide variety of devices, including cellphones.
* Qualcomm: They were also a significant player in the GPS chip market, especially for mobile devices.
* Government Agencies: The US military, through the Department of Defense, was responsible for the development and operation of the GPS system itself.
Determining who made the *most* equipment would depend on what metric you're using:
* Number of Units Sold: Garmin and Magellan likely held the lead in handheld GPS receivers.
* Overall Revenue: Trimble and SiRF might have had higher revenue due to their focus on professional applications and chipsets.
* Impact on Technology: Qualcomm and SiRF were vital for making GPS accessible to a wider audience through mobile devices.
Therefore, it's impossible to say definitively who made the *most* GPS equipment and technology in 2000 without a more specific definition of what "most" means.
