Apa itu GPS?

GPS (Global Positioning System) merupakan sistem navigasi satelit yang dikembangkan oleh Departemen Pertahanan Amerika Serikat (US DoD = United States Department of Defense). GPS memungkinkan kita mengetahui posisi geografis seperti ( lintang, bujur, ketinggian dan kecepatan di atas permukaan laut ). Jadi dimanapun kita berada di muka bumi ini, kita dapat mengetahui posisi kita dengan tepat dan akurat.

Sistem ini dikembangkan oleh Departemen Pertahanan Amerika Serikat, dengan nama lengkapnya adalah “NAVSTAR GPS” kesalahan umum bahwa ”NAVSTAR” adalah sebuah singkatan ini adalah salah, “NAVSTAR” adalah nama yang diberikan oleh John Walsh, seorang penentu kebijakan penting dalam program GPS.

Sistem navigasi satelit lainnya yang sedang dikembangkan oleh negara lain adalah:

* Beidou — Sistem lokal di RRC yang akan dikembangkan menjadi sistem internasional bernama COMPASS.

* Galileo — Sistem yang sedang dikembangkan oleh Uni Eropa, dengan bantuan dari RRC, Israel, India, Moroko, Arab Saudi, Korea Selatan, dan Ukraina.

* GLONASS — Sistem milik Rusia yang sedang diperbaiki.

* Indian Regional Navigational Satellite System (IRNSS) — Sistem yang dikembangkan India.

Ada pun kegunannya adalah sebagai berikut :

* Militer

GPS digunakan untuk keperluan perang, seperti menuntun arah bom, atau mengetahui posisi pasukan berada. Dengan cara ini maka kita bisa mengetahui mana teman mana lawan untuk menghindari salah target, ataupun menetukan pergerakan pasukan.

* Navigasi

GPS banyak juga digunakan sebagai alat navigasi seperti kompas. Beberapa jenis kendaraan telah dilengkapi dengan GPS untuk alat bantu nivigasi, dengan menambahkan peta, maka bisa digunakan untuk memandu pengendara, sehingga pengendara bisa mengetahui jalur mana yang sebaiknya dipilih untuk mencapai tujuan yang diinginkan.

* Sistem Informasi Geografis

Untuk keperluan Sistem Informasi Geografis, GPS sering juga diikutsertakan dalam pembuatan peta, seperti mengukur jarak perbatasan, ataupun sebagai referensi pengukuran.

* Sistem pelacakan kendaraan

Kegunaan lain GPS adalah sebagai pelacak kendaraan, dengan bantuan GPS pemilik kendaraan/pengelola armada bisa mengetahui ada dimana saja kendaraannya/aset bergeraknya berada saat ini.

* Pemantau gempa

Bahkan saat ini, GPS dengan ketelitian tinggi bisa digunakan untuk memantau pergerakan tanah, yang ordenya hanya mm dalam setahun. Pemantauan pergerakan tanah berguna untuk memperkirakan terjadinya gempa, baik pergerakan vulkanik ataupun tektonik.

GPS terdiri dari 3 segmen: Segmen angkasa, kontrol/pengendali, dan pengguna:

• Segmen angkasa: terdiri dari 24 satelit yang beroperasi dalam 6 orbit pada ketinggian 20.200 km dan inklinasi 55 derajat dengan periode 12 jam (satelit akan kembali ke titik yang sama dalam 12 jam). Satelit tersebut memutari orbitnya sehingga minimal ada 6 satelit yang dapat dipantau pada titik manapun di bumi ini. Satelit tersebut mengirimkan posisi dan waktu kepada pengguna seluruh dunia.

• Segmen Kontrol/Pengendali: terdapat pusat pengendali utama yang terdapat di Colorodo Springs, dan 5 stasiun pemantau lainnya dan 3 antena yang tersebar di bumi ini. Stasiun pemantau memantau semua satelit GOS dan mengumpulkan informasinya. Stasiun pemantau kemudian mengirimkan informasi tersebut kepada pusat pengendali utama yang kemudian melakukan perhitungan dan pengecekan orbit satelit. Informasi tersebut kemudian dikoreksi dan dilakukan pemuktahiran dan dikirim ke satelit GPS.

• Segmen Pengguna: Pada sisi pengguna dibutuhkan penerima GPS (selanjutnya kita sebut perangkat GPS)yang biasanya terdiri dari penerima, prosesor, dan antena, sehingga memungkinkan kita dimanapun kita berada di muka bumi ini (tanah, laut, dan udara) dapat menerima sinyal dari satelit GPS dan kemudian menghitung posisi, kecepatan dan waktu.

Bagaimana cara kerja GPS?

Setiap satelit mentransmisikan dua sinyal yaitu L1 (1575.42 MHz) dan L2 (1227.60 MHz). Sinyal L1 dimodulasikan dengan dua sinyal pseudo-random yaitu kode P (Protected) dan kode C/A (coarse/aquisition). Sinyal L2 hanya membawa kode P. Setiap satelit mentransmisikan kode yang unik sehingga penerima (perangkat GPS) dapat mengidentifikasi sinyal dari setiap satelit. Pada saat fitur ”Anti-Spoofing” diaktifkan, maka kode P akan dienkripsi dan selanjutnya dikenal sebagai kode P(Y) atau kode Y.

Perangkat GPS yang dikhususkan buat sipil hanya menerima kode C/A pada sinyal L1 (meskipun pada perangkat GPS yang canggih dapat memanfaatkan sinyal L2 untuk memperoleh pengukuran yang lebih teliti.

Perangkat GPS menerima sinyal yang ditransmisikan oleh satelit GPS. Dalam menentukan posisi, kita membutuhkan paling sedikit 3 satelit untuk penentuan posisi 2 dimensi (lintang dan bujur) dan 4 satelit untuk penentuan posisi 3 dimensi (lintang, bujur, dan ketinggian). Semakin banyak satelit yang diperoleh maka akurasi posisi kita akan semakin tinggi. Untuk mendapatkan sinyal tersebut, perangkat GPS harus berada di ruang terbuka. Apabila perangkat GPS kita berada dalam ruangan atau kanopi yang lebat dan daerah kita dikelilingi oleh gedung tinggi maka sinyal yang diperoleh akan semakin berkurang sehingga akan sukar untuk menentukan posisi dengan tepat atau bahkan tidak dapat menentukan posisi.

Bagaimana GPS digunakan?

Perangkat GPS menerima sinyal dari satelit dan kemudian melakukan perhitungan sehingga pada tampilan umumnya kita dapat mengetahui posisi (dalam lintang dan bujur), kecepatan, dan waktu. Disamping itu juga informasi tambahan seperti jarak, dan waktu tempuh. Posisi yang ditampilkan merupakan sistem referensi geodetik WGS-84 dan waktu merupakan referensi USNO (U.S. Naval Observatory Time).

Siapa yang dapat menggunakan GPS?

GPS dipergunakan pada berbagai bidang antara lain, sistem navigasi pesawat, laut dan darat, pemetaan dan geodesi, survei, sistem penentuan lokasi, pertanian, eksplorasi sumber daya alam, dan masih banyak lagi.

Apakah GPS itu gratis?

Teknologi GPS dapat digunakan oleh siapa saja, yang kita butuhkan hanya membeli perangkat penerima GPS dan selanjutnya informasi posisi dapat kita dapatkan tanpa membayar apapun.

Bagaimana akurasi GPS?

GPS memiliki dua tingkat ketelitian:

• Sistem posisi standar (standard positioning system / SPS)

SPS merupakan yang disediakan untuk umum (sipil). Tingkat akurasi yang dihasilkan adalah 100 m untuk posisi horisontal dan 150 meter untuk posisi vertikal.

• Sistem posisi presisi (precision positioning system / PPS)

PPS digunakan oleh Departemen Pertahanan AS dan tidak disediakan untuk umum.

Sejak Mei 2000, Pemerintah AS telah meningkatkan akurasi untuk SPS dengan menon-aktifkan SA (selective availability) hingga 20 meter untuk posisi horisontal.

Apa saja perangkat GPS itu?

Perangkat GPS ada bermacam-macam dan umumnya tergantung dari tujuan dan aktivitas yang akan kita lakukan. GPS untuk udara (aviation GPS) akan berbeda arsitekturnya dengan yang akan kita gunakan untuk navigasi di darat/mobil. Secara umum perangkat GPS dibagi menjadi 3 (tiga) fungsi yaitu navigasi udara (aviation), laut (marine) dan darat (land).

Apakah GPS juga Kompas?

GPS itu bukan Kompas magnetik, kecuali disebutkan bahwa perangkat GPS tersebut memiliki fungsi sebagai kompas magnetik sehingga anda tahu dimana arah Utara. Namun demikian GPS dapat memberitahu arah mana kita BERGERAK, sehingga kita dapat mengetahui dimana arah Utara. Apabila anda tidak bergerak, maka arah yang ditnjukkan kemungkinan benar SALAH.

Perangkat GPS apa yang cocok buat saya?

Mulai saja dengan perangkat GPS yang sederhana. Selain harganya terjangkau dan anda bisa membiasakan diri menggunakan GPS dan mengerti kebutuhan anda yang sebenarnya. Ada beberapa vendor GPS yang tersedia, diantaranya Garmin, Magellan, Trimble, dan Leica. Hal yang paling penting adalah, apapun perangkat GPS yang anda beli, pastikan bahwa perangkat tersebut memiliki 12 channel penerima untuk mendapatkan hasil yang memuaskan.

Saya memiliki GPS dan saya tetap tersesat!!

Masalahnya bukan pada GPS-nya, tetapi cara anda menggunakannya. Anda harus memahami cara kerja perangkat GPS anda dengan baik. Luangkan waktu untuk membaca manual dan petunjuk pemakaian.

Saya memiliki PDA, apakah dapat memiliki fungsi GPS juga?

Anda dapat menambahkan perangkat GPS pada PDA anda. Anda dapat memilih perangkat GPS-CF atau Bluetooth GPS, atau bahkan perangkat GPS biasa. Masing-masing memiliki kelebihan dan kekurangannya. Silahkan googling aja dech kalo mau tau banyak . Intinya, PDA anda ditambahkan perangkat GPS dan instalasi perangkat lunak yang mendukung dan selanjutnya silahkan bergembira dengan GPS anda. Bagaimana menyambungkan perangkat tersebut dengan PDA anda, semuanya diterangkan dengan jelas dalam manual perangkat GPS yang bluetooth atau CF yang anda beli.
