  1. wow what happen with spacebee 161 & 165 ? both altitudes are very low, only 210 km.

  2. more details of my 3 orders helical band pass filter:

    insertion loss

    at 137.8 Mhz (Spacebee / Swarm) approx 1.52dB (SWR 2.36)

    at 137.06 Mhz (Starlink) approx 1.08dB (SWR 1.273)

  3. dari data telemetri lora yang didapat dari @tinygs, lalu di masukkan ke aplikasi google earth, kita bisa melihat dengan sangat jelas perbedaan ketinggian rata - rata antara satelit gaofen, spacebee, dan starlink.

    urutan dari paling tinggi ke paling rendah :
    gaofen, spacebee, starlink.

    untuk gaofen sendiri terbagi lagi. ada yang atas dan bawah. yang bawah hampir sama dengan spacebee.

  4. If you open @tinygs web console, you will find the radiating map as below. from the heatmap we can find out the radiation pattern of the antenna we are using and the distribution of the satellite that the lora board receives.

    after i double checked, i realized that there is an altitude difference between 137mhz and 433 mhz satellites. 433 satellites like #gaofen 21,22,23,24 operate at 800km. norby at 550km. while 137 satellites like #starlink and #spacebee are at 300-500km.
