Power GNSS

From Your Pocket to the Podium: Tune Your RC Car with the Precision of a Pro

Imagine the frustration: you’ve spent hours building your RC car, tweaking the suspension, and balancing the tires. Yet, on the track, you’re a second off the pace. You know the car has more potential, but you’re relying on a phone’s GPS—which updates once per second and is accurate to several meters. That delay is the difference between clipping the apex and bouncing off a curb. Power GNSS is the tool that obliterates that gap. It transforms your Android device into a high-precision telemetry logger, capturing your speed, track position, and lap times with a stunning refresh rate of up to 10 Hz and centimeter-level accuracy. This isn’t a game in the traditional sense; it’s a professional-grade diagnostic app that turns every practice session into a data-rich test bench, letting you see exactly where you gain and lose time.

Core Telemetry & Data Analysis Tools

This application connects directly to external Bluetooth GNSS receivers (like the SkyRC GNSS module) to bypass the limitations of your phone's built-in sensor. The result is a live, scrolling dashboard of your vehicle’s performance metrics, displayed with the clarity of a racing simulator’s HUD.

• Live Lap Timing & Sector Splits: Define a start/finish line on the map. The app automatically detects crossing and logs each lap. You can set up to 10 split points per track, allowing you to isolate your performance in specific corners or straight sections. The on-screen display updates in real-time, showing your current lap time, last lap time, best lap time, and the delta to your personal best.
• High-Resolution Speed & Altitude Graphs: The core data view presents a dual-axis chart. The X-axis is time, the left Y-axis is speed (in km/h or mph), and the right Y-axis is altitude. As you drive, a line traces your speed in real-time. You can pinch-to-zoom on any section of the graph to analyze acceleration out of a hairpin or braking into a chicane. A second trace shows altitude changes, which is critical for tuning on undulating tracks.
• Multi-Session Comparison Mode: This is where the app becomes a true coaching tool. You can load two or more recorded sessions (e.g., "Run 1 - Soft Tires" vs. "Run 2 - Hard Tires"). The app overlays their speed traces on the same graph. You can then scrub through the lap side-by-side, visually identifying where one setup gained 0.3 seconds. The difference is shown as a colored delta band on the chart.
• Google Maps Track Overlay: After a session, you can export your data. The app plots your driven line as a colored path overlaid on Google Maps, with the color gradient representing speed (red for slow, green for fast). This gives you an immediate, intuitive visual of your racing line and where you are losing momentum.

Key Advantages That Set This Tool Apart

This is not a casual speedometer app. Its design philosophy centers on accuracy, repeatability, and deep analysis, making it a genuine asset for competitive RC racing.

• Professional-Grade Data Rate (10 Hz): While phone GPS updates at 1 Hz (once per second), Power GNSS processes data from external receivers at 10 Hz (ten times per second). This captures the subtle micro-movements of your car—a tiny oversteer correction, the exact moment you hit the brakes. This granularity is essential for serious tuning.
• Automatic Track Detection & Session Management: The app doesn't just record data; it organizes it. It can automatically detect when you start a new run based on movement. All data is stored in a structured log with timestamps, track names (which you can rename), and a summary of your best lap. You can easily export these logs as CSV files for import into spreadsheet software for further analysis.
• Zero-Latency Bluetooth Connection: The app establishes a direct, low-latency Bluetooth connection to the GNSS receiver. This means the data you see on the screen is happening now, not half a second ago. This is crucial when using the live speed readout to test the immediate effect of a gear change or motor timing adjustment.
• Battery-Conscious Background Operation: The app is designed to run for a full day of racing. It uses efficient data polling and allows you to dim the screen during long practice sessions without stopping the data logging. A persistent notification shows your current connection status and recording state.

Stop guessing why you’re fast or slow. Start measuring. Power GNSS gives you the same data analysis tools used by professional race engineers, adapted for your RC car and your Android device. Whether you’re chasing a national championship or just shaving a tenth off your personal best at the local track, this app provides the objective feedback you need to improve. Download it now and turn every lap into a lesson.

Disclaimer: This application requires a Bluetooth Low Energy (BLE) compatible external GNSS receiver (e.g., SkyRC GNSS module) to function. It is not a standalone GPS tracker. The application is intended for use in model sports and RC racing. Continuous use of GPS running in the background can dramatically decrease battery life. This app may include in-app purchases for optional features or data export capabilities. An active internet connection is required for map overlay features. By downloading, you agree to the terms of service. Not recommended for children under 3 years of age. Data usage is minimal but dependent on map tile loading.
