Introduction of GPS Survey & RTK GPS
Similarly Many private Technology practices require significant investment. Therefore, an Precise cost estimate is Elementary for the success of any project.
Moreover, Many earth surfaces rely on basic Geography, and, therefore, Cartographer use topical Cartography to gather Necessary and Applicable data.
However, Inaccurate GPS survey results in a Geography map that does not represent the construction area will make a biased or Incorrect investment.
RTK AND GPS SURVEY :
Similarly Since survey-based private companies work in a competitive business environment. But also there is a need to demonstrate that they are above others in terms quality and that their strategic direction is more realistic and focus.
GPS Survey Government Entities:
Moreover, They must provide Convenient as well as Precise Approaches to gain their Customer’s confidence. Therefore, they always Suggest the newest, most precise, and most Practical methods in line with their financial Competencies in gps survey.
Over the past decade Real Time Kinematic, RTK Fieldwork with Global Navigation Satellite Systems (GNSS) has become common practice in Cartography.
Additionally RTK and GPS survey is a relative Placement technique that measures positions using two GNSS Aerials in Immediate.
Moreover, The base station, known as such, is set up on a static point with fixed Location.
It uses a high-frequency radio to transmit its raw observations to the second unit (known as the rover) and then the rover. Uses both observations to compute a position relative to the base location in real-time.
Similarly RTK survey requires reliable communication between base and rover units and works. Best with short baselines as the precision of RTK measurements decreases as the baseline length increases
Evaluation of GPS-RTK and Total Station for Topographic Survey and Strategic Decision in Private Companies
Abstract GPS Survey
Survey-based private companies need an accurate and efficient survey system to thrive in the business and engineering world.
Specifically We investigated the accuracies of the GPS Survey – RTK (Global Positioning System – Real Time Kinematic) system and TS (Total Station) in a topographic survey.
Likewise The hypothesis proposed was that the GPS Survey -RTK system could be an alternative survey for moderate accuracy projects. 5.90 ha salt ponds area became a sample for the research.
Both instruments conducted a full detailed measurement for constructing a contour map. We recorded time expenditure to assess the effectiveness of each method. The maximum offset of elevation was 0.054 m (polygon) and 0.098 m (detail).
Moreover, The GPS survey results demonstrated that even though the GPS-RTK system was not only practical and efficient (time-saving reached 30% versus TS and 33% more efficient in human resources).
While yielding acceptable accurate topographic maps for moderate accuracy engineering purposes, the GPS-RTK system cannot be applied to every terrain feature.

Consider the GPS-RTK (Global Positioning System – Real-Time Kinematic) system. But also The most useful system for topographic surveys between satellite survey technologies.
Utilization of this system for surveys of multi-functional networks and, sometimes, also the detailed 3rd order network, is becoming more popular.
The factor which makes surveys using the RTK measuring set more difficult within specific areas is the presence of terrain obstacles.
Additionally, These can limit the simultaneous communication of the basic receiver and the mobile receiver as well as interfere with the necessary communication among the five satellites required for GPS Survey to be 100% reliable.
RTK- GPS SURVEY:
GPS- RTK based surveys are not only practical and fast but also yield more accurate topographic maps for design purposes (for an open area with no obstacles and using a model to generate contours).
Indeed numerous construction and estate monitoring processes, Total Station (TS) is employed for observations. Moreover, It’s asserted that TS is a more suitable method for topographic surveying in private companies within Indonesia, whether undertaken by the owner, contractor, or consultant, compared to using a Theodolite.
Not only does this instrument provide good accuracy. But also provides automatic computation for the data. Total Station observation achieves only a 1 mm standard deviation.
Similarly The focus of this research is to evaluate the accuracies of the RTK survey by Geodetic.
GPS Survey and Tachometric survey by TS in land surveying for construction practices, both for medium (cm class) and high (mm class) accuracy projects (this test was for land trade’s practice).
The following specific objectives facilitated the achievement of this goal:
1. Evaluating the result and accuracy obtained from GPS-RTK and TS.
2. Using supervised classification to perform data analysis provided from each data source.
3. Comparing the contour map provided from each data source; and
4. Evaluating the cost (time expenditure) of both systems.
GPS SURVEY
What is GPS Survey?
The full meaning of GPS Survey is the Global Positioning System. The internet can be used to determine the location of road ghats in any area.
With GPS we can know the latitude, longitude, altitude, time of a place and create different types of maps. GPS is the best tool for identifying a country’s borderline.
How is GPS Survey Used in Surveying?
GPS Survey and mapping were one of the first commercial adaptations of GPS, as it provides a latitude and longitude position directly without the need to measure angles and distances between points.
However, it hasn’t entirely replaced surveying field instruments such as the theodolite, Electronic Distance Meter, or the more modern Total Station, due to the cost of the technology and the need for GPS to be able to ‘see’ the satellites, therefore, restricting its use near trees and tall buildings.
In fact practice, surveyors often incorporate GPS technology into a Total Station to generate complete survey data.
Therefore, GPS receivers used for baseline measurements are generally more complex and expensive than those in common use, requiring a high-quality antenna.
There are three methods of GPS measurement that are utilized by surveyors.
- Surveyors use static GPS to determine accurate coordinates for survey points by simultaneously recording GPS. Observations over a known and unknown survey point for at least 20 minutes.
- Additionally We process the data in the office to provide coordinates with an accuracy of better than 5mm. Depending on the duration of the observations and satellite availability at the time of the measurements.
- Real-Time Kinematic (RTK) Observations. This is where one receiver remains in one position over a known point – the Base Station – and another receiver moves between positions – the Rover Station.
- Using a radio link, we can compute and store the position of the Rover within a few seconds, providing a coordinate correction.
- Continuously Operating Reference Stations (CORS). Likewise This is where surveyors permanently install a survey-quality GPS receiver as a starting point for any GPS measurements in the district.
- Common users of CORS are mining sites, major engineering projects, and local governments. Surveyors’ GPS receivers can then collect field data and combine it with the CORS data to calculate positions.
- Thus Many countries have a CORS network that is used by many industries. Australia’s CORS network is the Australian Regional GPS Network, and uses an online.
- Processing system to deliver data over the internet within 24 hours, and give positions within an accuracy of a few centimeters.
- Surveyors also use local CORS networks to provide instant positions similar to the RTK method by using a mobile phone data link to offer coordinate correction to the surveyor and their rover.
