#UNION OF COMOROS ISLANDS #TrimbleR780 #GNSS #Geodetic_Control_points #Triangulation #BOINGOMA_MOHELI_Comoros #port_construction #IHO_Standards Static GNSS (Global Navigation Satellite System) These points are established using static GNSS techniques, allowing for high-accuracy positioning over a defined area. Here’s an overview of the key aspects of static GNSS survey control points: ### Definition Static GNSS survey control points refer to fixed locations where GNSS receivers are set up for an extended period, often several hours to days, to collect satellite signal data. These points serve as reference locations for various surveying applications. ### Purpose 1. **Accuracy**: Static GNSS surveying provides high precision, often within a few centimeters, making it suitable for applications requiring exact measurements. 2. **Reference Stations**: Control points act as reference stations for real-time kinematic (RTK) or post-processed kinematic (PPK) surveys. 3. **Geodetic Networks**: They are essential for establishing geodetic networks, facilitating consistent measurements across different surveys. ### Setup Process 1. **Site Selection**: Choose a location with a clear view of the sky to minimize obstructions from buildings, trees, or other structures. 2. **Equipment**: Use high-quality GNSS receivers and antennas, ensuring they are properly calibrated. 3. **Observation Period**: The duration of data collection varies based on the required accuracy; longer observation times generally yield better precision. 4. **Data Processing**: The collected data is processed using specialized software to compute the exact coordinates of the control points. ### Applications - **Topographic Mapping**: Creating detailed maps for urban planning, construction, and environmental monitoring. - **Infrastructure Projects**: Providing control points for roadways, bridges, and utility installations. - **Geodetic Surveys**: Establishing reference points for national and regional geodetic systems. ### Advantages - **High Accuracy**: Static techniques yield more accurate results compared to mobile GNSS surveying. - **Stability**: Control points remain fixed, allowing for consistent reference for future surveys. - **Flexibility**: They can be used in various applications, from small local projects to large-scale national surveys. ### Conclusion Static GNSS survey control points are vital for achieving high-precision measurements in surveying and mapping. Their establishment and maintenance are crucial for ensuring the integrity and reliability of geospatial data used in various industries.

🚀 In recent years we are witnessing a new space revolution, driven by the emergence of new technologies, the reduction of entry barriers and the proliferation of new products and services using the space environment. As a result, new mission concepts based on manned flights, mega constellations, on-orbit servicing, microsatellites, etc. are emerging and consolidating, changing the paradigm concerning conventional systems. In this context of the aerospace sector, new challenges and trends have arisen from the perspective of systems engineering and RAMS. Pablo López Negro, Head of Innovation at ANZEN Engineering has analysed them in the V Space Engineering Congress organized by the Space Committee of the Spanish Institute of Engineering (IIE) (Comité del Espacio): 🔹 Reliability: the impact of New Space, the commercial context and new mission concepts have replaced the typical interpretation of reliability at satellite level by a global interpretation at mission level. 🔹 Availability: space missions have transitioned from providing a high value-added service but not critical for society to new missions where the continuity of service must be guaranteed. 🔹 Maintainability: except in rare cases, it has not been a common concern for missions until now, but that has changed, and new trends are emerging: new reusable launchers, mission concepts based on constellations with periodic satellite replacement or advances in on-orbit servicing. 🔹 Safety: with reinforced efforts required by new applications such as the renewed interest in human space flight or the increasing concern about planetary protection and sustainability of space operations. Pablo López also analysed the available solutions and emerging technologies to address these challenges in upcoming space missions. #SpaceInnovation #RAMS #SpaceInfrastructure #ANZENEngineering #Networking

Space missions providing critical services (such as communications, global positioning, or emergency response monitoring) require high availability. Human flights and vehicle re-entries into the atmosphere are subjected to strict safety policies. Scientific programs in outer space benefit from high reliability... and the overall increase of systems in orbit makes mandatory the adoption of mitigation and contingency measures to protect and preserve the space environment. 🛰️🌍 Considering all the above, the need to implement safety and dependability measures since early design phases becomes evident. Pablo López Negro, Head of Innovation at ANZEN Engineering, analyzed at the 2nd ESA RAMS Conference organized by the European Space Agency - ESA how the emergence of Model Based Systems Engineering (MBSE) has generated an opportunity to directly address these aspects from the mission concept and architectural models. This offers new tools to systems engineers to tackle safety and dependability related challenges all along the design and development process of complex space programs. 🚀🌌 🔹 Starting from the conceptual analysis of the mission, the safety framework allows signaling feared events and hazards, and identifying mitigations to be implemented in the operational concept and the design of the system from early phases of the systems’ life cycle, supporting also feasibility studies and design trade-offs. 🔹 At system architecture level, systems engineers could analyze the severity of functional hazards and determine the need for redundancies as well as setting reliability and availability objectives.  🔹Along the design and development phases, the framework allows keeping information up to date and ensuring consistency between design choices and results from dependability analysis. To that purpose, bridges between MBSE and domain-specific reliability and availability analysis tools are being implemented. In summary, the presentation discussed the state of the art of model-based safety and dependability analysis. #Space #SystemsEngineering #MBSE #SpaceSafety #Reliability #Innovation #ANZENEngineering #ESA #RAMS
