Surveying plays an integral role in the Infrastructural, construction, mining, surveying, railways, Engineering, Marine and Agricultural industries. As in most things technical, advances in technology and systems have brought about dramatic changes in surveying as laser mapping and scanning systems for topography. All these advanced surveying equipment promise greater accuracy and precision, durability, and robustness

The following firms are the leading surveying equipment manufacturers in the world:

Leica Geosystems

Formerly known as Wild Heerbrugg, Leica Geosystems is a Switzerland based company that produces products and systems for surveying and geographical measurement (geomatics). Its products employ a variety of technologies including GPS satellite navigation and laser range finders to enable users to model existing structures, terrains in computer-based systems to high accuracies, often under 1 cm.

The company has a team of well-qualified and competent team of engineers and consultants supports who have rich experience in the field of Scientific and Electronic instrumentation, control systems and Surveying Instruments that meet the exact requirement of their customers.

Topcon Inc.

Having a core business founded on the surveying instruments, Topcon Inc. have maintained a leading rank in survey equipment manufacturing since establishment in 1932. The company operates in three segments; the Positioning Business, which uses high-precision GNSS positing technology to achieve the automation of civil engineering construction and farming, the Smart Infrastructure Business, which applies the surveying technology the company have developed since their founding in the fields of infrastructure development and structural maintenance and management, and the Eye Care Business, which offers advanced solutions in the field of ophthalmology.

Thanks to the company’s network of production, development, and sales locations, Topcon products and services are used throughout the world with overall sales ratio of 79% in FY 2020. They have also expanded business domains through M&A and alliances. Topcon’s major hit product was in 1978 when the company released the DM-C1, the worlds smallest and lightest electro-optical distance measuring instrument and theRM-100, the world’s first refractometer to utilize near-infrared light and enable measurements utilizing on-screen operations via a TV monitor. These two products became explosive hits which brought about dramatic changes in Topcon’s company structure.

Trimble

From its start in 1978 above the old Los Altos theatre in Silicon Valley, Trimble has been driving a focus on developing innovative positioning and navigation products. By focusing its resources on harnessing and expanding the power of GPS through innovative products, Trimble spearheaded the rapid development of commercial and consumer applications, as well as military use of the new technology. Taking GPS from its exclusively military applications and applying it to traditional markets such as surveying and navigation would revitalize and redefine these markets, both highly dependent on positioning technology. Marrying GPS with other technologies, such as wireless communications, would spawn new and emerging markets that make use of position-centric information.

The company prides itself by being the company that introduced the world’s first commercial scientific-research and geodetic-survey products based on GPS for oil-drilling teams on offshore platforms. For over 38 years, Trimble has created unique positioning products that help customers grow their business. Trimble augments its organic product development with strategic acquisitions to bring the latest positioning technologies to a wider market
