Description

GPS rod

This GPS rod is a essential item you need to land survey it is a carbon, lightweight and very robust rod. It is detachable and with the carrying case easy to transport. As it is made from carbon it will be light weight. By using this carbon rod you can feel the difference if you need to use it for a long time. By having it in 2 meter height which is essential for you GNSS receiver. With the 2 meter you will have the GNSS reciver at a height that is essential for the RTK fix you need.

Length of GPS rod

For a GPS rod the length is very important. The normal length is 2 meters. That is the normal length because then the complete GPS rover kit is manageable. You can move it easy. And the distance between the GNSS receiver and the location where you hold it is not that big.

That means there is not much effort needed to move with the complete GPS rover kit.

Also with a length of 2 m the horizon that the GNSS receiver can receive satellite signals from is kind of big. Sometimes that is not enough though. There are locations where you even need a bigger horizon to be able to receive enough satellite signals.

And that is possible with a higher GPS rod. With a higher rod you increase the horizon. Even with an extra 20 centimeter the position given by the GNSS receiver can improve from a Float RTK to an RTK fix. So that can be a reason why the longer rod might be worth it for you.

Material of GPS rod

Then there is the material. The type of material of the rod tells you how strong the rod is and how light or heavy it is. In general there are two options:

  • aluminum
  • carbon

From origin the aluminum rod was used a lot. Because it is strong it is still used in heavy conditions. So it is a good material for a GPS rod. But it is heavier than its alternative. And the alternative is carbon.

A carbon rod is lighter than the aluminum one. And that means it is easier to work with it the whole day. Of course the carbon rods are also strong. They are good for normal conditions.

So the choice is up to you.

Connection

Besides the material and the length there is also an option in the connection method. That means the method how the rod makes the complete length. There are two options. And they all have their benefits.

  • screwable
  • telescopic

The nice thing of the screwable GPS rods is that the length when you are not using the rod is small. Usually it is around 1 meter or even smaller. That means that this type of rod is easy to store. Besides that the srewable rods are easy to set up in the field.

But there is also the telescopic option. This type of rod always exist of one piece. You can extend the rod by turning the screw and then lifting the piece that is inside the bottom part of the rod. This type of rod is even easier to set up in the field. And usually they are more easy to change the height of the rod. To do this you don’t even have to remove the GNSS receiver.

And that is a big plus, because you are more flexible in the field.

Amount of sections

So the telecopic rod comes in one piece or section. That is not always the case with the screwable rod. The amount of sections depends on the length of the GPS rod and on the length of the sections.

When the sections are shorter, there are more sections of the rod. That is easier to transport. In the field it will take a bit longer to set the GPS rover kit up.

So as mentioned the choice depends on the purpose you need the GPS rod for. If you have to move a lot from project to project then one with shorter and more sections might be the choice for you. But if you are usually working on just one project on a day then you don’t need that many sections.

Brand of GPS rod

Of course there are different brands in GPS rods. Almost every manufacturer of GNSS receiver also has its own GPS rod. And a rod of the same brand as the GNSS receiver would make a great combination.

But it is not necessary. Because as already mentioned the type of rod depends on the purpose you have for it. Maybe you want the GPS rod to be of aluminum, but the manufacturer won’t have a GPS rod in that material.

The same is valid for for example the length or amount of sections of the rod. Besides a GPS rod of one brand can be cheaper than the one of some other brand.

A GPS rod is essential when you want to do GPS land surveying. So when you want to land survey with a GNSS receiver you need a GPS rod.

But there are many different options and variants in GPS rods. The best rod depends on how you will use it. So the options you have for a GPS rod are:

  • length
  • material
  • connection type
  • amount of sections
  • brand

Faq

A GPS rod is used in GPS surveying for several reasons. First of all it keeps everything together. The GNSS receiver is mounted on top of the GPS rod. The tablet is connected to the GPS rod with a tablet holder. This makes it easy to carry the complete GPS surveying kit with one hand.
Another thing that is very important is that the GPS rod gives the GNSS receiver some height. This way the GNSS receiver can receiver more satellite signals. Because of the height less signals get blocked by obstacles like trees. So a GPS rod is very important in GPS surveying.

Carbon rods are used in GPS surveying, because they are light and strong. They can easily stand the weight of the GPS surveying kit. What carbon rods can’t stand is high torque and crushing loads. But those are not there when you GPS survey with a carbon rod.

You can do a lot of things with a carbon rod. One of them is GPS surveying. It is ideal for that because carbon is strong and light. That is also why carbon is used in Formula 1 cars. So the uses of carbon are countless. It is used everywhere where you need a strong and light material.

Carbon rods are made of graphitized carbon. In carbon there is Silicon, Aluminum, Iron, Magnesium, Calcium, Iron and Boron. The mix of it gives a as a result carbon, which is a light and strong material.

One of the elements in carbon is Iron. That makes it a good conductor. Carbon rods will conduct electricity well. That is why you have to be careful when you GPS survey with a carbon rod need powerlines or when you survey electric cables.

This is really a question with the answer it depends. It depends how you use the carbon rod. If you use it in a normal way than it can last for years. Of course there will be wear and tear, because of the use if it. But normally it will easily last more than 5 years.
