Elaborately discuss the GNSS survey planning process with the help of suitable examples and diagrams, wherever required.

The Global Navigation Satellite System (GNSS) survey planning process involves several steps to ensure accurate positioning and data collection using GNSS receivers. This process includes considerations such as selecting appropriate survey techniques, establishing control points, determining satellite availability, and optimizing survey configurations. Let's discuss each step in detail, supported by examples and diagrams where applicable.

1. Define Survey Objectives: Begin by clearly defining the survey objectives. Determine the desired accuracy requirements, the area to be surveyed, and the specific data to be collected. For example, if the objective is to create a detailed topographic map, the accuracy requirements will be higher compared to a simple cadastral survey.

2. Select Survey Technique: Choose the appropriate survey technique based on the objectives, accuracy requirements, and the environment in which the survey will be conducted. Common techniques include static, kinematic, and real-time kinematic (RTK) surveys.
