Hello @Ryan-Min,
As far as I know, there is no specific CAD model file for the GPS mast. You should use the complete CAD model of the Starling 2 Max drone, which is available for download in the developer download section. You will need to create an account.
Here is a direct link to the most recent version of the model, the version V3 : D0012-4-V3-C28-M36-T7-K0-Starling2-Max-V3-20260317.step
The latest changes to the model are intended to improve GNSS performance. You can consult the documentation page EMI Mitigation for GNSS Applications for more information on this topic and to see their recommendations.

@Alex-Kushleyev
That's not perfect but I created a shell script based on https://docs.modalai.com/qgc-via-adb/ for the drone configuraiton.
For my PC configuration, I created an udev rule to force an interface name since usb0 is renamed in "enx******". My udev rule can only work with my drone (I think). To define IP address, I add a conf file in /etc/systemd/network/
I have only tested on my linux and it works perfectly :

#!/usr/bin/env bash
set -euo pipefail

@Alex-Kushleyev, thank you for your answer.
I confirm your assumption, when I set the decimator to 1, the fps is not divided.
Here are the tests I did on SDK 1.5.0 and SDK 1.6.3 :

test with SDK 1.5.0 ;

As you can see, for SDK 1.5.0, fhe fps is NEVER divided, regardless of the value of standby_enabled.
For SDK 1.6.3, fhe fps is ALWAYS divided, regardless of the value of standby_enabled.
So, my problem is solved but I think you have a bug on the management of the paramater 'standby_enabled'.
I fastly investigate the code of voxl-camera-server and I can't find where you are using 'standby_enabled'. Here is the search result in all the project :

# Query: standby_en
# ContextLines: 2

6 results - 2 files

include/common_defs.h:
  370      modal_exposure_msv_config_t  ae_msv_info;  ///< ModalAI AE data (MSV)
  371  
  372:     int     standby_enabled;       ///< Standby enabled for lidar
  373      int     decimator;             ///< Decimator to use for standby
  374  

src/config_file.cpp:
  129          printf("    gain_min           : %d\n", cams[i].ae_msv_info.gain_min);
  130          printf("    gain_max           : %d\n", cams[i].ae_msv_info.gain_max);
  131:         printf("    standby_enabled:     %d\n", cams[i].standby_enabled);
  132          printf("    decimator:           %d\n", cams[i].decimator);
  133          printf("    independent_exposure:%d\n", cams[i].ind_exp);

  642          // standby settings for tof only
  643          if(is_tof_sensor(cam->type)) {
  644:             json_fetch_bool_with_default(item, "standby_enabled", (int*)&cam->standby_enabled, cam->standby_enabled);
  645              json_fetch_int_with_default  (item, "decimator", &cam->decimator,   cam->decimator);
  646          }

Maybe you should add a condition in your function PerCameraMgr::ProcessTOFPreviewFrame():

void PerCameraMgr::ProcessTOFPreviewFrame(mpa_ion_buf_t* buffer_info, camera_image_metadata_t meta)
{
    tofFrameCounter++;

    if(grab_cpu_pitmode_active() && tofFrameCounter % (int)configInfo.decimator != 0){
        return;
    }
    auto noStridePlaneSize = static_cast<size_t>(pre_width*pre_height*1.5);
    auto realWidth = static_cast<uint32_t>(pre_width*1.5);
    uint8_t* noStridePlane;
    if (buffer_info->stride != realWidth) {
        noStridePlane = new uint8_t[noStridePlaneSize];
        removePlaneStride(buffer_info->stride, realWidth, buffer_info->height,
                          (uint8_t*) buffer_info->vaddress, noStridePlane);
    }
    else {
        noStridePlane = static_cast<uint8_t*>(buffer_info->vaddress);
    }

    uint16_t srcPixel16[pre_width * pre_height] = {0};
    // NOTE we don't actually puvblish tis particular metadata to the pipe
    // TOF data is published separately in a very different way to cameras
    meta.format     = IMAGE_FORMAT_RAW8;
    meta.size_bytes = pre_width * pre_height;
    meta.stride     = pre_width;

    Mipi12ToRaw16(meta.size_bytes, noStridePlane, srcPixel16);
    tof_interface->ProcessRAW16(srcPixel16, meta.timestamp_ns);

    if (buffer_info->stride != realWidth) {
        delete[] noStridePlane;
    }
    M_VERBOSE("Sent tof data to royale for processing\n");

    return;
}

I would like to report a probable bug related to the TOF camera on my Starling 2 Max (configuration C29).
I was previously running SDK 1.5.0, and the TOF camera was operating correctly at the frame rate specified in the file "/etc/modalai/voxl-camera-server.conf".
I recently upgraded from SDK 1.5.0 to SDK 1.6.3 (I didn't try other SDK versions).
Since then, the TOF camera runs at a frequency divided by 5. I tested this using the CLI inspection tool with the command "voxl-inspect-cam tof_depth" for different FPS values (same results in VOXL-Portal). I have not changed anything on the drone except the "fps" parameter in the configuration file "/etc/modalai/voxl-camera-server.conf".
Here is my TOF camera configuration:

"type": "pmd-tof-liow2",
"name": "tof",
"enabled":      true,
"camera_id":    3,
"fps":  10,
"en_rotate":    true,
"ae_mode":      "off",
"gain_min":     0,
"gain_max":     0,
"exposure_max_us":      6000,
"standby_enabled":      false,
"decimator":    5

Here are the results from "voxl-inspect-cam tof_depth" for different FPS values:

fps = 5
| Pipe Name |  bytes  | wide |  hgt |exp(ms)| gain | frame id |latency(ms)|  fps |  mbps  | format
| tof_depth |   43200 |  180 |  240 | 48.00 |    0 |       26 |     28.1  |  1.0 |    0.3 | RAW8

fps = (8, 12, 25, 35, 40, 45, 50, 65, 70, 75, 80, 85, 90, 100, 120, 135, 140, 150, 180)

| Pipe Name |  bytes  | wide |  hgt |exp(ms)| gain | frame id |latency(ms)|  fps |  mbps  | format
| tof_depth | Server Disconnected

Looking at the code in "src/hal3_camera_mgr.cpp", it seems expected that other frame rates do not work anymore. Here is the relevant section:

if (configInfo.type == SENSOR_TOF){
    if (configInfo.fps != 5 && configInfo.fps != 10 && configInfo.fps != 15 && configInfo.fps != 30 && configInfo.fps != 45){
        M_ERROR("Invalid TOF framerate: %d, must be either 5, 10, 15, 30, or 45\n", configInfo.fps);
        return -1;
    }
}

if (configInfo.type == SENSOR_TOF_LIOW2){
    if (configInfo.fps != 5 && configInfo.fps != 10 && configInfo.fps != 15 && configInfo.fps != 20 && configInfo.fps != 30 && configInfo.fps != 60){
        M_ERROR("Invalid TOF framerate: %d, must be either 5, 10, 15, 20, 30, or 60\n", configInfo.fps);
        return -1;
    }
}

Thanks in advence

Hello everyone,

We’ve been following this discussion with great interest — especially the insights about the mast kit and the copper shielding solution. We also tried similar approaches on our side and wanted to share our results to contribute to the thread.

We purchased four Starling 2 Max drones for our project at the beginning of the year, and like others here, we are experiencing difficulties with GPS stability outdoors. To mitigate interference, we designed and 3D-printed our own GPS mount to move the antenna away from the main body, and we added a copper shielding layer around it.

We then tested the u-blox M10 GPS outside, under clear sky conditions, with the drone powered on (connected via Wi-Fi to use VOXL-Portal). Over about 10 minutes, the best observation we captured showed 18 satellites with an average SNR around 30–35 dB.

However, despite these results, we still cannot achieve a stable outdoor localization, which currently prevents us from flying the drones properly outside. At this point, we’re unsure whether the problem comes mainly from the GPS performance or possibly from the barometer.

We’d really appreciate:

Being included in your support list for this GPS issue, since it affects multiple units on our side (as mentioned by @Alex-Kushleyev).
Any guidance or recommendations on how to debug further (extra shielding, hardware setup, barometer validation, software settings, etc.).

Thanks a lot to the ModalAI team and to the community for the shared ideas — we hope our feedback helps others as well.

Best regards,

Quentin
