Choosing the right receiver

When choosing the right GNSS receiver, you need to consider your application requirements.  What environment will you be working in – open space, built-up areas, under canopy?  What level of cm accuracy do you need?  How rugged does the device need to be?

MGISS has worked with almost every brand out there, so we’re perfectly positioned to offer impartial advice on the best GNSS receiver for your needs.  We’ve helped many customers trial different brands ensuring they purchase the right device for them.

All Leica and Eos receivers work seamlessly with all GIS software and with any Android, iOS or Windows mobile devices, enabling you to benefit from existing hardware.

However, if you don’t have existing mobile devices, MGISS can recommend the best devices based on your business requirements.

As the authorised UK distributor for Leica Zeno and Arrow Series® GNSS Receivers, MGISS can provide a fast turnaround for sales and hires of all the receivers and accessories.

What our customers say:

“Devices have worked reliably and effectively, allowing us to collect accurate GPS data for our regional network of monitoring stations in the UK. This has helped us to save time when locating monitoring devices and reduce the number of errors when working in the field. I would highly recommend MGISS as a supplier for GPS and GIS devices.”

“It has been straightforward and made simple, through the user-friendly setup. The kit has allowed us to capture underground assets in a speedy fashion and with the most accurate means of recording the location of them too, down to the centimetre. The end product we are left with is both clean and precise, where unnecessary clutter is never an issue.”

Chris McCarte, Energy Assets

“It’s the speed needed to operate the business. We understand our network better. Unfortunately, it used to take 80 days from a main being laid to it going onto our records. With GNSS we can do it live.”

Martin Oliver, Severn Trent


GNSS receivers receive and process signals from GNSS satellites to provide data related to position, velocity and time.

Precise point positioning (PPP) technology makes it possible to achieve centimetre-level accuracy in real-time on any continent when there is no base station and connection to a regional reference station network or mobile internet is unavailable.

The process of generating corrections with PPP technology works similarly to RTK bridging. The only difference is in the correction data sent to the geostationary satellite which contains parameters and information that allow a centimetre-level position to be computed independent of any other RTK correction data.

The latest developments in these technologies enable users to stream RTK bridging and PPP correction data over the mobile internet to compatible GNSS sensors, providing a way to ensure continuous availability and coverage anywhere in the world.

A feature that allows RTK users to work effectively in areas where wireless connectivity is inconsistent.

With SafeRTK®, the Arrow Gold® receiver keeps you productive even in areas with spotty cellular reception. It maintains centimeter-level accuracy by seamlessly switching between RTK network corrections and satellite corrections, all using the same reference point.

Positioning services are an add-on for your GPS or GNSS (Global Navigation Satellite System) device that improves its accuracy. Here’s how it works:

  • Regular GPS/GNSS can give you good positioning, but it might be off by a few meters.
  • These correction services use a network of reference stations to pick up on errors in the signal from the satellites.
  • They then calculate corrections and send them to your device via various methods like internet, satellite, or cellphone signals.
  • With these corrections applied, your GPS/GNSS can achieve much higher accuracy, sometimes down to centimeters!

Country/Region of Origin: Each constellation is developed and operated by a different entity.

  • GPS (US), Glonass (Russia), Galileo (EU), BeiDou (China)

Number of Satellites & Accuracy: The number of satellites in operation can affect accuracy. GPS generally has the most satellites (around 30 operational), while GLONASS has slightly fewer (around 24). This can lead to slightly better accuracy with GPS (typically 3.5-7.8 meters) compared to GLONASS (5-10 meters).

  • GPS is the most mature and widely used system- the grandaddy of them all
  • Galileo offers a good alternative and is interoperable with GPS.
  • GLONASS is a viable backup to GPS.
  • BeiDou is a growing system with a focus on China and surrounding areas.
