GNSS receivers and how they work in agriculture and others

how GNSS receivers work

Global Navigation Satellite Systems or GNSS receivers are satellite navigation receivers used to measure position, velocity, and time. GNSS receivers are beneficial for agriculture, surveying, land management, etc. In precision agriculture, GNSS receivers can collect information to determine how to use resources for the most efficient output. It can include how much water should be applied for irrigation or how much fertilizer to use on crops. In addition, agribusiness uses the GNSS constellation of satellites to provide a precise location on the Earth's surface. GPS receivers can be used in handheld applications, in-vehicle applications, and building-mounted applications. They are often the default choice for precision farming applications since they are available at a meager cost, require no external antennas, and work indoors. Since the GNSS receivers have a lot of advantages in some ways besides agriculture, many businesses utilize it to enrich their field works. Here are how GNSS receivers work in some industries. 


GNSS receivers as a tool for surveyors 

GNSS receivers are a must tool for surveyors as they face many challenges—for example, the growing complexity of the land. Buildings, trees, power lines, and other artificial objects have made it increasingly difficult to measure the land accurately. Traditional methods of land measurement, like the chain and the theodolite, are slow, inefficient, and often yield incorrect measurements. Hence, they use GNSS to measure accurate distances and angles and collect data on the position of objects. 


GNSS receivers as a tool for drafters 

Construction companies use GNSS receivers to find their locations, build maps of their buildings' areas, create 3D models of buildings, digital elevation models (DEMs), or other structures. Some construction companies use a fleet of vehicles to deliver equipment and materials to construction sites. The GNSS receivers can help drafters navigate the roads and highways near their locations and determine the most efficient routes to their sites, saving them time and money.


GNSS receivers as a tool for geologists 

The part of the geologist's job relies on satellites, which are expensive and time-consuming to obtain. Instead, a geologist can use a GNSS receiver, which uses satellites but is much cheaper and faster to use. They use the GNSS receiver to map out landmasses like mountains or valleys. Besides, they can measure distances between two points on the Earth's surface and plot them on a map to discover the shape and size of areas under investigation, which can help them plan their exploration strategy. 


Choosing a single-band or multi-band RTK GNSS receiver

When starting a project, one of the first decisions is whether to use single-band or multi-band receiver technology. Choosing the right receiver technology for your project is essential because it can impact your project costs and the accuracy of your measurements. In detail, the following is the overview of single-band and multi-band RTK GNSS receivers. 


Multi-band GNSS receivers

A multi-GNSS receiver is a device that can determine position, velocity, and time by receiving signals from numerous navigation satellite systems. The advantage of the multi-GNSS receiver is it can boost positioning success rates by collecting plenty more satellite signals even under challenging conditions.

Single-band GNSS receivers

A single-band GNSS receiver only receives one frequency band transmitted by the satellites. It is the right choice for businesses with open environment projects at a lower price.
