NASA Reveals Challenges In Transmissioning PACE Satellite Data

JAKARTA Satelliteambah, Aerosol, Cloud, ocean Ecosystem (PACE) successfully transmits the first operational data from space. Despite the success of transmission, PACE satellites remain facing challenges.NASA says that all satellites orbiting in space will produce important data, including PACE satellites. Important data supporting this satellite's goals must be sent to Earth via radio waves. Unfortunately, the satellite data delivery process is not always going well. The distance between satellites and network receiver stations on Earth often faces problems such as buffering, delaying, and damaged links. In order for such problems to be resolved, NASA uses two different network stations, namely the Deep Space Network and Near Space Network. Especially for Near Space Network, NASA added a Tolerant Networking (DTN) Disruption Network network. This network is integrated into four new antennas on the Near Space Network. DTN supports communication for missions in space, but is limited to a distance of 1.2 million miles. PACE is the first satellite to use such networks." PACE is the first operational science mission that utilizes DTN and we use it to transmit data to mission operators that monitor batteries, orbits, and more, "said NASA Assistant Assistant SCAN Kevin Coggins.

Pejabat NASA SCaN itu mengatakan bahwa DTN sangat berguna bagi satelit PACE dan satelit lainnya di masa depan. Pasalnya, jaringan tersebut akan, "memberikan perlindungan kuat terhadap data yang mungkin hilang karena gangguan."Satelit PACE diluncurkan pada Februari lalu dan saat ini sudah berada di ketinggian 250 mil dari permukaan bumi. PACE digunakan untuk mengumpulkan variabel atmosfer yang berkaitan dengan kualitas udara dan iklim serta mempelajari fitoplankton.Mikroskopis atau tumbuhan air yang sangat kecil ini diamati untuk mengetahui kesehatan laut. Harapannya, seluruh data yang dihasilkan bisa memberikan pemahaman mengenai keadaan laut dan saluran air serta dampaknya terhadap Bumi.
