Trimble Static Survey Method: How We Doing Static Survey in Trimble GPS GNNS system

In This Video We Discuses ON Static Survey Method: How we start Static Survey, How We connect GNNS Receiver Rover and Its working After Start Static Work, We Will Explain in this Video . 1. Introduction to Static GPS/GNSS Static GNSS surveys deliver the highest-accuracy positions available in a system, which occupies a point for longer periods of time than kinematic systems. Static systems include a range of survey styles from rapid static surveys to continuously operating stations, such as CORS and PBO sites. The equipment setup varies significantly, depending on how long the site will be operational, which could vary from 15 minutes to several years. For the practicality of this field module, instructional material will focus on surveys ranging from rapid static to semi-permanent installations. Continuously operating permanent stations require many of the same techniques as other static systems, but require a level of precision and detail in their installation and processing that is beyond the level of this course. Static surveys rely on long occupation times to produce high-accuracy positions, and the details of their setup will vary to reflect the quality of measurements required. A static survey typically consists of a single receiver and antenna combination, which individually records satellite observations that are post-processed using a variety of techniques to receive a position. The precision of the position is a function of the length of survey and also the precision of the mounting and monument system used. Static surveys require much more stable and precise mounts than kinematic surveys. A typical mounting system ranges from a range pole and bipod for rapid static occupations to anchored rods with direct antenna mounts for permanent surveys. 1.1 Rapid Static Survey Rapid static surveys use shorter occupation times to collect a moderate number of points. They do this by occupying a given point for a longer period of time than most kinematic surveys but much less than regular static surveys (Section 1.2 below); typically, rapid static surveys are 15 minutes to 2 hours. A static survey is advantageous due to the simplicity of its setup, using a single antenna and receiver combination that has half as many components as a kinematic setup. This configuration is also necessary when radio communications or baseline distances for a survey exceed the capability of a kinematic design. However, static surveys typically have reduced accuracy compared to a kinematic survey of the same occupation time. Rapid static surveys also rely on proximity and availability of CORS or IGS stations for positional corrections. 1.2 Static Surveys Static surveys offer the second highest precision of static surveys by occupying a single location for occupation times ranging from 2 to 48 hours. When processed through OPUS, static surveys have a maximum accuracy of ~1–2 cm, depending on the quality and length of data collection. This is most comparable to accuracies achievable by PPK systems with long baselines, but in general PPK surveys are recommended if a local base station with short baseline is possible. Static surveys are conducted and processed in the same way as a rapid static survey, but typically use higher-precision mounts and more equipment, such as large batteries, solar panels, and equipment enclosures to support the GNSS receivers during the length of the survey. The amount of equipment needed increases with increased occupation times. See Section 2.3 for advice on batteries and length of surveys with some known hardware configurations. trimble,trimble access,trimble gps,trimble connect,tremble,trimble ag,trimble dr,trimble s7,trimble ri,trimble dbo,trimble r10,trimble rtk,trimble r12i,trimble gfx750,trimble dealer,sitech trimble,trimble guidance,trimble s-series,trimble buildings,trimble geospatial,trimble access 2021,trimble agriculture,trimble construction,trimble support videos, SketchUp trimble connect,tremble cover,trimble connect visualizer
