Arguably, the most important thing to know before purchasing equipment is the parameters of your project. There are several things to consider, including; what level of accuracy is required, the size of your site, time constraints, and the overall budget. Having an idea of these requirements before you begin searching for your equipment will help you avoid any buyer’s remorse.
Considerations for Your Survey Equipment Purchase
The Choice of Accuracy
One of the largest factors to consider when determining the equipment that will work best for you is the level of accuracy you require. Do you need a sub-meter or a sub-centimetre measurement? Depending on your desired level of accuracy, the options available to you will change.
For sub-meter projects, where a high degree of accuracy is not required, a single GNSS receiver is the right way to go. These devices are more commonly known as GIS receivers and provide positions within a beach ball-sized area. These kinds of instruments are particularly useful for utility management and commercial irrigation. When rough positioning is all that is required, a GIS receiver is generally the answer.
The more precise of the two, sub-centimetre, is required for projects where positions must fit within a golf ball-sized area. Many different types of surveying equipment can provide the required level of accuracy for these projects. Here at Bench Mark, the most common packages we sell for this solution are GNSS RTK Bases and Rovers, or a GNSS RTK Network Rover.
Both of these options provide similar levels of accuracy but provide different advantages and disadvantages. Some of the other options available for this accuracy level include manual and robotic total stations. Although they provide a higher degree of relative accuracy when compared to GNSS RTK receivers, they come with their own considerations to be made before purchasing.
The two aspects that are most overlooked during surveying equipment purchases are the size of the project and the time allotted for the survey. Depending on the combination of factors you have, different pieces of equipment will suit your needs.
For projects that take place over a small site, no more than 800-1000 metres, where the site is wide open and free from obstructions, a manual (MTS) or robotic total station (RTS) will be the answer to your needs. With a smaller site, you can set up on one point and survey the entire area. When taking a robotic total station onto a larger or more crowded site, you may have to move and reposition your total station several times to survey the entire site which leads to unnecessary downtime and introduces more chances for errors.
With a robotic total station, you have the ability to perform the entire survey with a single individual, potentially saving you time and labour costs. A robotic total station will automatically track the user around the site while the user records data remotely. This contrasts with a manual total station, where a two-person crew is required. This kind of setup often takes more time than an RTK, as each shot must be manually focused and recorded.
For project sites under 10 kilometres in radius, an RTK GNSS Base and Rover is the best solution. With this type of survey equipment, a base receiver can be set in a position where it will then broadcast, over UHF radio, to the rover’s receiver. This type of system allows you to cover large areas and complete surveys quickly.
For sites larger than 10 km in radius, a network rover is the best option. A network rover will be able to provide a precise position within a golf ball-sized area, however, it only works if network coverage is present. If this sounds like something you would be interested in, StormCaster devices may be the answer for you. However, it is important to note that if there is a lapse or inconsistency in your cell coverage, you may want to look into a base radio or signal enhancer. This will help a base and rover achieve more range.
The Choice of Time and Site Size
The Choice of Cost
We know how important cost is when buying a new piece of surveying equipment. Keeping your budget in check and buying the right piece of surveying equipment to fit your needs is a crucial part of any purchase.
For those on a very limited budget, but still looking for a high degree of accuracy, a manual total station is likely the answer. However, before buying a manual total station, it should be noted that they require two operators. Carefully weigh the pros and cons of having two people using the equipment versus the outright cost of a more expensive solution.
For those who are looking to use more high-tech options, the choice is between a robotic total station and an RTK GNSS system. Both of these options bring way more convenience than a manual total station. They can be used by a single individual and they can cover a much larger area in a smaller time.
Finding the balance between these factors can make the difference between a successful purchase, and one that ends in disaster.
