GPS速度テスト
GPS速度計オンライン
ZpeedでGPS速度計をブラウザから確認できます。準備ができてから計測を開始してください。
Verify your dash.
Your phone's GPS gives a precise digital readout, useful when you want to see how closely your vehicle's display matches actual speed.
Speed without hardware.
Mount your phone on the bars and read live pace without pairing a sensor or magnet. Works as long as you have open sky above you.
Know your outdoor pace.
Track km/h or mph in real time on outdoor runs. GPS measures movement across the ground, so it will not register on a treadmill.
Train, bus, or ferry.
Sit back on any vehicle and see exactly how fast you are moving. No app needed, just a browser and a clear GPS signal.
ブラウザGPSでGPS速度計
Zpeedは端末の位置情報を使ってGPS速度計を km/h、mph、m/s で表示します。ネイティブアプリは不要で、許可後にのみ追跡が始まります。
一部のブラウザや端末では Geolocation API の対応に制限があります。位置が正確でない場合は GPS を有効にし、ブラウザとページに位置情報の許可を与えてください。
GPS速度計が便利な場面
GPS速度計は移動中、通勤、短い確認、車載メーターが見づらい場面で役立ちます。
GPS精度を上げるには
GPS速度計をより正確に使うには、屋外または窓際でZpeedを開き、GPS信号が安定するまで待ってください。
Good to know
Things worth knowing.
01 How accurate is a GPS-based browser speedometer? ⌄
In open sky, modern phones usually get a strong GPS fix and can estimate speed reliably. Accuracy drops in tunnels, indoors, under heavy tree cover, or between tall buildings.
02 Does Zpeed ask for location on page load? ⌄
No. Zpeed shows the speedometer first and only asks for location after you tap Start tracking and continue through the in-app explanation.
03 Does my location leave my device? ⌄
No. The live GPS speed calculation runs in your browser. Zpeed does not require an account or server-side location tracking for the speedometer.
04 Which speed units are supported? ⌄
Zpeed supports km/h, mph, and m/s. The selected unit is saved in your browser.
