Question 1

How Accurate are e-Survey GNSS RTK systems?

Accepted Answer

Modern GNSS RTK systems can provide a relative accuracy of 0.8cm +/- 1ppm horizontal and 1.5cm +/- 1ppm in the vertical. This relative accuracy can be translated into absolute accuracy using Monuments. All the GNSS RTK systems Tec-Niche provides are capable of this level of accuracy.

Question 2

How much does an RTK GPS system cost?

Accepted Answer

Modern GNSS RTK GPS systems are comparable in price to robotic total stations, while providing a much higher level of productivity. As with robotic total stations, prices will vary depending on the manufacturer. With Tec-Niche and e-Survey, you will receive the best value for your money.

Question 3

How long does an RTK battery last?

Accepted Answer

The e-Survey receivers come with either hot-swappable batteries or with internal battery packs. With the hot-swappable battery configuration, each will last approximately six hours of. Depending on the receiver and the application, the internal batteries will last 10-12 hours. This battery life can be extended using e-Survey’s external power kit, which provides 16 hours of base operation; so, the e-Survey RTK GPS battery can last between 6 and 16 hours.

Question 4

Does your product have all the constellations activated?

Accepted Answer

Hemisphere GNSS receivers come fully loaded with the ability to track and make measurements from all 5 satellites constellation.

Question 5

How accurate is the receiver without receiving base corrections?

Accepted Answer

An e-Survey GNSS receiver can achieve 20-25 cm in X & Y in DGPS mode with just one WASS satellite. It can also achieve 4-8 cm in X & Y in L-Band mode via Atlas global correction service H-10 service without being in RTK mode.

Question 6

What kind of range can I get with these units?

Accepted Answer

All the receivers we carry come with at least a built-in 1- or 2-watt radio. Our E800 has an internal 5-watt radio for a range of 10-12 kms. The typical range for our units is 5 – 6km in ideal conditions. If you need to go farther than this, Tec-Niche offers many options to extend your range, whether you need a base booster radio like the TRU35, or a network option like NTrip Caster, we have what you need to get the job done.

Question 7

Why does Hemisphere Machine Control cost less than Trimble and Topcon?

Accepted Answer

Hemisphere has been making GNSS components for the past 30 years, initially being introduced to the OEM, Marine and Agricultural GNSS markets. In the last 8 years, they have focused on the Land Surveying and Construction markets. To gain rapid market share in these markets, Hemisphere GNSS has introduced very aggressive pricing and advanced RTK GNSS technology within these industries. Test it yourself and experience the difference!

Question 8

Does your product have all the constellations activated?

Accepted Answer

Hemisphere GNSS receivers come fully loaded with the ability to track and make measurements from all 5 satellites constellation, included in the base price of our Machine Control Systems.

Question 9

How well does Hemisphere Machine Control (GradeMetrix) work in poor conditions?

Accepted Answer

Because of the inclusion of five major constellations as a standard, GradeMetrix can pull data from a complete range of satellites for better reception, lower on the horizon. GradeMetrix works well close to structures, in valleys and under thick canopy.

Question 10

How difficult is it to get started with GradeMetrix Machine Control?

Accepted Answer

Most operators that have not tried machine control of any type agree that using something new can be quite daunting. Whether you a new operator or an experienced one, GradeMetrix uses a very simple user interface that is intuitive and easy to understand.
