GNSS Accessories That Can Improve Field Productivity

Satellite navigation systems such as GPS and GNSS have revolutionised the surveying industry. Across a wide range of surveying tasks, GNSS surveying methods can offer high levels of precision and accuracy at an unparalleled speed and with innovative technologies like Precise Point Positioning (PPP) emerging over the past decade, even remote locations or areas with limited visibility can be tackled with confidence and efficiency with GNSS surveying.

But if you want to push your field productivity even further, you need to ensure you have the right GNSS accessories on hand. Whether it’s a powerful, versatile data collector to deliver valuable insights or a robust transport kit to keep your equipment safe, high-quality GNSS accessories can have an enormous impact on your surveying workflow.

In this post, we’ll break down all the essential gear you need to deliver an efficient, effective GNSS survey. We’ll highlight the key benefits and give you tips on what to look for when deciding on the right accessories for you.

As we’ve explained in a previous post, data collectors are the most versatile devices in the field. These handheld devices are a portable data powerhouse, providing real-time control of your GNSS receiver, seamless data logging and storage, and the ability to run powerful surveying software like Trimble Access directly on-site.

With a data collector, surveyors can streamline their workflows, eliminate the need for manual data entry, and make informed decisions in real time based on the data collected. They also enable seamless integration with other surveying tools, improve overall project management, and offer the flexibility of offline functionality in remote areas.

Needless to say, the productivity gains offered by these versatile devices are second to none. When it comes to adding accessories to your GNSS surveying kit, a data collector should be at the top of the list.

Data collectors are powerful tools, but the features they offer will depend on the model you choose. If you’re looking to add a data collector to your kit, it’s essential you pick the right one for your needs. Key features to consider include:

• Processing power. If you have significant data demands, look for a faster processor and a larger amount of RAM. This will ensure your data collector can handle large datasets and perform complex calculations with ease.

• Battery life. If you’re spending long days out in the field, battery life is paramount. Prioritise data collectors with extended battery life or, even better, those with hot-swappable batteries so you can keep working without powering down.

• Durability. If you work on demanding job sites, make sure your data collector can withstand the harsh conditions. Otherwise, unexpected breakdowns or accidents might undermine any productivity gains.

• Software compatibility. If your data collector doesn’t seamlessly integrate with your existing surveying software, you may find that compatibility issues require frustrating and time-consuming workarounds.

A data collector is a significant investment, but if you pick the right model for your requirements, you’ll see major productivity gains across your GNSS surveying workflow.

The Trimble TDC6 is the ideal choice if you want to combine power and portability. If you work on demanding job sites but still need access to powerful and efficient data processing, the TDC6’s 2.7GHz octa-core processor and 6GB of RAM will certainly do the trick. It uses the Android 12 operating system for efficiency and ease of use while offering worldwide 5G compatibility to minimise any connectivity issues.

What is more, all this comes in a lightweight and durable package. The TDC6 weighs just 287g, and its IP67 rating ensures that it’s both dust- and waterproof. If you’re spending long days in the field and contending with hazardous conditions, it’s the ideal choice.

The Trimble TSC5 is the perfect blend of performance and reliability. Its 5” touchscreen is easy to use with a finger or stylus – even if you’re wearing gloves! – and the anti-glare display means it’s visible in all conditions and its highly ergonomic design means you’ll have no trouble carrying it around on sites and using its powerful 2.2 GHz processor to help streamline your surveying workflows.

For those looking for truly cutting-edge functionality and advanced data processing capabilities, the Trimble TSC7 is the ideal option. With comprehensive connectivity options and the ability to handle large project files and 3D imagery, the TSC7 is a handheld powerhouse that can supercharge your productivity. And thanks to its hot-swappable batteries, you’ll be able to keep the work going through long, demanding days in the field.

When it comes to your productivity in the field, few things have a bigger impact than battery life. If your GNSS receiver runs out of battery midway through the working day, your ability to collect data, stake out points, or perform other crucial tasks comes to an abrupt halt. You may need to return to your vehicle or office for a recharge, costing you valuable time and potentially delaying project timelines.

This makes replacement batteries and portable charging solutions indispensable tools if you’re serious about maximising efficiency in your GNSS surveying activities. Thankfully, many manufacturers offer spare and replacement batteries for their GNSS receivers. Trimble, for instance, can supply spare Li-ion batteries for its most popular receivers, including the cutting-edge R12 and R12i models.

You’ll also want to ensure that your batteries are all charged and ready to go when you head out on a job site. If you do invest in spare batteries, you should also consider exploring different charging options such as Trimble’s dual slot battery charger.

Real-time kinematics (RTK) offers a flexible and highly efficient approach to GNSS surveying. With a base-and-rover setup, you can achieve centimetre-level accuracy in real-time, eliminating the need for post-processing and reducing the potential for costly errors. RTK is also a great option for covering large areas at a pace without sacrificing detail.

But for an effective base-and-rover surveying workflow, you don’t just need GNSS receivers that are up to the task. You’ll also need robust rover rods and versatile adapters to ensure your antenna is perfectly positioned and your data collection is accurate and efficient.

The right rover rod makes it easier to achieve the ideal height for your GNSS receiver, reducing the risk of signal loss in areas with limited visibility. It can also help reduce the impact of any vibrations or unexpected jolts, which might otherwise impair the accuracy of your readings.

For the maximum productivity benefits, ensure your rover rod is lightweight and durable – a carbon fibre rod like the SECO 2.5m Metric Grad Fixed Tip GPS Rover Pole will help keep your kit manageable and reduce fatigue. And if you’re looking to speed up your setup and maximise your productivity in the field, choose a snap-lock rover rod for convenience and ease of use.

When it comes to finding the right adapter, compatibility is key. You’ll want to make sure the adapter you choose is designed to work seamlessly with both your specific GNSS antenna and rover rod models. It should securely attach the antenna to the rod without any wobbling or looseness, ensuring stable measurements. Also, consider the type of connection mechanism and choose one that suits your workflow and preferences – a quick-release adapter is a great choice if speed and simplicity are your top priorities.

RTK surveying methods, alongside other Differential GNSS (DGNSS) approaches, allow you to achieve the sub-centimetre accuracy required by most surveying projects. But as we’ve explained in our previous post on base stations, the base-and-rover setup has its limitations. A limited operational range may mean you need multiple base station setups to cover a larger project area, while obstructions can easily block the signal between the two receivers.

But just as total station surveys have been transformed by the development of the robotic total station, GNSS surveys have continued to evolve. The emergence of advanced real-time correction services in recent years has removed the need for a separate base station in many scenarios. As a result, these subscription-based services can significantly improve the speed and accuracy of your GNSS surveys.

These services can be divided into two main categories: Virtual Reference Station (VRS) services and Precise Point Positioning (PPP) services. While the former can help you survey large areas at a pace, the latter offers unparalleled accuracy with global reach.

Let’s look more closely at the benefits of each.

VRS services

Virtual Reference Station (VRS) services utilise a network of Continually Operating Reference Stations (CORS) to replace the physical base station commonly used in RTK surveys. This not only avoids any risk of base station failure disrupting your surveys, but it also means you won’t need multiple base station setups to cover large project areas.

If you’re looking to achieve centimetre-level accuracy over a wide area without the hassle of establishing and maintaining your own network of base stations, a service like Trimble VRS Now is the ideal choice. With instant access to a continually monitored CORS network and coverage available across North America, Europe and APAC regions, it’s perfect for streamlining your workflow and minimising downtime.

Trimble RTX

Trimble RTX is a precise point positioning (PPP) service that takes the accuracy advantages of VRS and extends them across the globe while reducing the risk of connectivity issues.

While VRS services still require the rover to transmit its position to the VRS network over a mobile connection to receive real-time corrections, Trimble RTX provides correction data via L-band satellites without any need for a two-way connection.

As a result, you ensure high levels of accuracy in areas with fewer reference stations and you won’t have to worry about your mobile signal dropping out. With Trimble RTX, you can achieve centimetre-level accuracy at pace, no matter where in the world you’re based.

Trimble RTX is ideal for surveying projects that are based in remote areas or require maximum accuracy over large areas. It’s also well-suited for applications where mobile coverage is unreliable, as long as there’s a clear view of the sky for satellite reception.

When it comes to productivity in the field, it’s easy to focus on the most exciting additions to your kit: the cutting-edge data collectors, the latest GNSS receivers or the most advanced correction services. But something as simple as having a durable, lightweight and ergonomic way of carrying and storing your kit can have a significant impact on your workflow.

After all, your GNSS system is only as effective as your ability to transport and protect it. A damaged receiver or a misplaced cable can bring your survey to a grinding halt, costing you valuable time and money.

When looking for cases and kits for your GNSS surveying equipment,

you’ll need to balance protection with portability and organisation. You’ll want to make sure that your cases and kits are rugged enough to withstand the rigours of the field, but also that they’re not so bulky and cumbersome that they become a burden to carry.

And it may be an obvious point, but it’s vital that you’ll have space for all your essential gear. That’s why it’s worth looking at cases and kits supplied by the manufacturer of your GNSS surveying equipment. For instance, Trimble offers a full range of cases, pouches, and backpacks designed to perfectly accommodate their receivers, controllers, batteries, and other accessories. This ensures a snug, secure fit that maximises protection while minimising bulk, keeping your gear safe without adding too much extra weight.

When it comes to improving your operational efficiency and protecting your bottom line, field productivity is an essential consideration. But your GNSS surveying work doesn’t end once you leave the field – in fact, it’s just the beginning. Once you’re back in the office, you’ll need to process your data, analyse the results, and transform raw measurements into meaningful deliverables for your clients or stakeholders. This is where office software steps in as your indispensable post-processing partner.
