Abstract

GNSS (Global Satellite Navigation System) merupakan suatu istilah yang digunakan untuk mencakup seluruh sistem satelit navigasi global yang sudah beroperasi ataupun sedang dalam perencanaan. Sistem navigasi satelit global ini beberapa diantaranya yaitu GPS, GLONASS, dan BeiDou. Kesalahan akibat sedikitnya satelit saat pengambilan data, secara teoritis dapat teratasi dengan kemajuan teknologi receiver yang mampu menangkap berbagai sinyal satelit. Hi Target V30 adalah salah satu receiver GNSS yang mampu menangkap sinyal satelit GPS, GLONASS dan BeiDou, dengan semakin banyaknya sinyal satelit yang dapat diterima diharapkan dapat meningkatkan akurasi dari penentuan posisi. Dari penelitian ini menunjukkan bahwa penggunaan satelit BeiDou tidak terlalu memberi pengaruh terhadap satelit GPS, akan tetapi penggunaan satelit BeiDou menambah ketelitian dari satelit GLONASS. Hal ini ditunjukkan dengan adanya penurunan nilai pada selisih koordinat dan RMS error yang dihasilkan dari 1.068 m menjadi 0.371 m. Penggunaan kombinasi satelit GPS + GLONASS + BeiDou dan GPS + GLONASS rata – rata menghasilkan ketelitian yang paling kecil dengan nilai RMS error yang tetap berada diangka millimeter, sedangkan penggunaan satelit GLONASS saja menghasilkan ketelitian yang paling besar diantara stategi yang digunakan terlihat dari nilai RMS error yang mencapai 0.585 m pada baseline C2

Abstract

The influence of school principal leadership, principal motivation at work, and principal entrepreneurial skills on elementary school teacher performance in the Cikande District is the subject of this study. The method used was multiple linear regression analysis using a quantitative approach. The results of the study showed that all three elements, independently and in combination, had a good and considerable influence on teacher performance. Revealing an Adjusted R Square value of 0. 565, the multiple coefficient of determination (R²) reveals a 56% influence of the combined effect of the independent variables leadership, work motivation, and the principal'sentrepreneurial skill on the dependent variable (teacher performance) Effective school principal leadership can help create a pleasant work environment and advance professionalism among teachers. High work motivation from principal work motivation creates enthusiasm and role models that drive optimal teacher performance. Meanwhile, the principal’s entrepreneurial competence encourages innovation and creativity in managing education, which positively impacts improving teacher performance. These findings indicate that the synergy all three variables together can create a productive and quality teacher performance system.
