Antenna architecture matters
Select a heading receiver by its hardware arrangement
This SIYI RTK product combines positioning and dual-antenna heading in one module. It is a useful candidate when a survey UAV project calls for a separately identified heading receiver rather than a basic GNSS puck. The catalog calls it the RTK Positioning and Orientation Module; the listing here uses “heading” to make that navigation role clearer in English.
| Product distinction | This RTK module | Why the distinction matters |
|---|---|---|
| Heading architecture | One module with two antenna connections | Specify the corresponding antennas and system support. |
| Compass | PNI RM3100 | Keep the model's own component specification. |
| Related F9P option | A separate product with a different described architecture | Do not merge two receiver specifications into one offer. |
A compact module is only part of the installed package
The receiver measures 40 × 30.5 × 15mm and is listed at 22.8g, with 1W power consumption. Those values describe the module. Two antennas, their cables, any bracket and the rest of the navigation installation need a separate weight and space allowance. The catalog operating temperature range is −30 to 75°C; the proposed accessories should be assessed for the intended environment as well.
GPS, GLONASS, BeiDou, Galileo and QZSS are the named satellite systems. The RM3100 compass belongs to the receiver's documented hardware description. A broad constellation list or a compass name should not be turned into a guarantee that obstruction, installation or interference can never affect the navigation result.
Define the receiver package before requesting a price
Identify the flight controller, the civil survey or inspection application and whether positioning alone or positioning plus heading is required. Ask the supplier to name the actual module revision, included antennas, cables and controller support. The single-module arrangement is the important starting point when comparing this product with an offer that uses more than one receiver.
If a quote names only “SIYI RTK,” request the full product description. The catalog contains both this positioning-and-heading module and an F9P RTK product. Similar terminology does not make the hardware, accessories or supported configuration interchangeable.
RTK module selection questions
- Is this the same product as F9P RTK?
- No. SIYI lists them separately. This entry uses a single module and two antennas; keep each model's architecture and specifications distinct.
- Does 22.8g include the antennas?
- It is the catalog module figure. Ask for the weight of the exact antenna and cable package being supplied.
- What does the heading specification apply to?
- The catalog ties the 0.2° figure to a 1m antenna baseline. It should remain a qualified manufacturer figure rather than a universal aircraft guarantee.
