POB rolls out its Total Station survey in a searchable, user-friendly online format; manufacturers present advanced technologies offerings.





2007 Total Station Survey

Total stations continue to be the most important component of the tools used by surveyors today. The demise of the total station that some predicted when GPS (and particularly RTK GPS) was first introduced, has not happened. If anything, total stations have experienced a renewed vitality to make them work more productively with GPS, especially on the data front. The technology of reflectorless measurements, servo-driven target-seeking and target-tracking total stations continues to improve. The addition of Bluetooth technology to data collectors, originally to serve RTK users, continues to be added to more models of total stations so users can enjoy cable-free surveying.

Manufacturers with broad lines of products tend to have robotic, reflectorless instruments at the high end and manual instruments with phase-resolving EDMs that require a retroprism at the low end. Descriptions of most product lines, however, do not stop there. There is added complexity: application software can be “universal” so that it can be used in a number of applications, or it can be customized for particular sub-areas of surveying, such as construction, setting out and quality control. Features such as light guides for setting out, necessity of an external data collector, and the ubiquitous flexibility in angle and distance accuracy, as well as measurement distance range, necessitates understanding the subtle differences even between the same manufacturer’s models. Managers involved in the selection of instrumentation can perform a more thorough needs assessment and have the ability to better tailor the company’s purchasing choice to those needs.

This February, POB is excited to announce that its 2007 Total Station survey is now available in an online searchable, comparable format. As part of our efforts to supply POB readers with superior information, we are extending all of our print surveys to this multi-media format. Our exclusive listing of specifications is the same as previous years, and is limited to information on the six most popular series from each manufacturer. The specifications highlighted will allow you to gain a better understanding of a company’s total station features and abilities.

Leica Geosystems

Leica SmartPole

The SmartPole is the latest addition to the Leica System 1200 product family. It saves time in both the office and field. It is no longer necessary to first measure orientation points and only then detail points. Simply begin the survey and conduct the setup while completing the survey. Once the TPS orientation and coordinates are known, all measured points are automatically updated. With the Leica SmartPole, both TPS and GPS are available at all times to ensure every point can be measured. When GPS is restricted by overhead obstructions, use TPS. When no TPS line-of-sight is available, use GPS. Benefit from easy-to-use GPS and continuous productivity with Leica’s SmartPole.

A Smart Investment

The Leica SmartStation, SmartPole and SmartRover are fully compatible with System 1200, sharing the same common user interface, common data management, common functions and features. Also, users who have already invested in a SmartStation or SmartRover can be assured that their investment is secure. The same SmartAntenna can be used together with a TPS1200 as a SmartStation, together with a RX1250 controller as a SmartRover or together with a 360 reflector and RX1250 controller as a SmartPole. Common hardware components reduce costs and increase the flexibility of equipment deployment.

PENTAX

Two new series of Pentax total stations will debut this year: the R-300DNX and R-800. The R-300DNX models have a built-in digital image camera and reflectorless, sheet and prism measuring. Angle accuracies are 2, 3 and 5”. Internal data collection is the same as the current R-300NX and EX series.

The R-800 models come in both NX (reflectorless, sheet and prism) and EX (sheet and prism) series. Angle accuracies are 2, 3 and 5” in each series. The R-800s have built-in Windows CE data collection with a 400MHz processor, USB port, CompactFlash port and Secure Digital slot. The color display is 3.7 in diagonal with 640x480 pixels. A 33-key user interface makes input simple and quick.

The R series also have automatic environmental sensing. The environmental correction (PPM) is calculated from data supplied by electronic temperature and pressure sensors. The operator does not need to measure or input this data; rather, the instrument automatically takes care of this. All R series, except the DNX, have image focusing which has been automated with an auto and power focus push button capability. Manual focus can also be used for special situations.

In addition, absolute encoders are used for faster startup, improved vertical angle accuracy and more consistent horizontal reference angle orientation. The narrow visible beam allows users to see the exact measurement point and obtain accurate distances in tighter spots than ever before. A visible laser plummet increases setup speed and the IPX6 waterproofing provides serious weather protection.

Trimble

The Trimble S6 Total Station features innovative technologies--MagDrive servo technology, MultiTrack technology and SurePoint accuracy assurance--that provide unequalled advantages to surveyors.

Based on the principles of a magnetic drive, the patented MagDrive servo technology makes the Trimble S6 Total Station fast (115 degrees per second), silent and precise, even when fully transiting 360º horizontally or 180º vertically.

With its MultiTrack technology, the Trimble S6 Total Station locks and tracks to conventional prisms and actively checks the Target ID. With the ability to use eight different targets on a single site, MultiTrack ensures that the Trimble S6 Total Station is always aiming at the correct target.

SurePoint accuracy assurance enables the Trimble S6 Total Station to remain accurately aimed, even if slightly moved. When the instrument is aimed manually at the target, the servo drive goes into hold mode. If the instrument is bumped, SurePoint makes fine adjustments back to the original aimed angle. SurePoint continually corrects for mislevelment and errors such as collimation and trunion axis tilt.
