Context: Kuno National Park Director Uttam Kumar Sharma clarified that satellite collars fitted on cheetahs do not provide continuous live tracking.

  • The clarification followed the death of KNG22, a male cheetah found seriously injured in the Sheopur territorial forest division on October 25 and later died during treatment.
  • The Madhya Pradesh government suspended six Forest Department officials in connection with the incident.

How Satellite Collars Work

  • Location updates, not live tracking: Satellite collars provide the geographical location of an animal at a particular point in time; they do not continuously transmit its movements.
  • Transmission frequency: At Kuno, collars are generally programmed to transmit location data at six-hour intervals.
  • Missed transmissions: If one scheduled update is missed, the gap may increase to 12 hours; if two consecutive updates are missed, it may extend to 18 hours.
  • Cost and battery constraints: Each collar costs approximately ₹4–5 lakh. Transmission frequency is determined by balancing monitoring requirements, battery life and the expected duration of collar use.
  • Signal interruptions: Temporary loss of satellite signals may occur due to dense forest canopy, rocky terrain, caves and deep valleys, which can obstruct GPS signal reception or satellite visibility.
  • Delayed response: By the time location information reaches monitoring teams and personnel travel to the reported coordinates, the animal may have moved several kilometres away.

Wildlife Monitoring at Kuno

  • Around 15 cheetahs are monitored through a combination of satellite collars and radio receivers.
  • Satellite collars: Provide location information over large and often inaccessible landscapes.
  • Very High Frequency (VHF) radio receivers: Help field teams locate animals more precisely on the ground by detecting signals from the collars.
  • The two technologies are complementary: satellite tracking identifies the last reported location, while VHF equipment assists in locating the animal in the field.

Challenges of Tracking Cheetahs

  • High mobility: Cheetahs move an average of 6–8 km per day and may cover 12–15 km or more on several occasions.
  • Movement patterns: Their movements are often concentrated during early morning and late evening hours.
  • Terrain constraints: Following cheetahs on foot is extremely difficult, while monitoring vehicles cannot move through forests in straight lines like animals.
  • Consequently, the actual distance travelled by a monitoring vehicle may be several times the straight-line distance between two locations.
  • By the time teams reach the last reported satellite location, the cheetah may have moved beyond the team's VHF radio range.

Important Concepts for UPSC

  • GPS vs Satellite Communication
    • GPS (Global Positioning System): A satellite-based navigation system that enables a receiver to determine its geographical position.
    • Satellite communication: Uses satellites to transmit information, such as location data, from a device to a receiving station.
    • A GPS-enabled collar may determine an animal's location, but the location data still needs to be transmitted and received. Therefore, GPS-based positioning does not automatically mean continuous live tracking.
  • VHF (Very High Frequency) Radio
    • VHF radio operates in the 30–300 MHz frequency range.
    • It is used in wildlife monitoring to detect radio signals emitted by tracking collars.
    • Its effectiveness depends on factors such as terrain, vegetation, distance and receiver capability.

Prelims Question

Q1. With reference to satellite-based wildlife tracking, consider the following statements:

  1. A GPS-enabled collar can determine an animal's geographical position without necessarily transmitting that information continuously to a monitoring station.
  2. Satellite communication and GPS perform identical functions in wildlife tracking systems.
  3. Dense forest canopy and deep valleys may interfere with the transmission or reception of location signals.
  4. Periodic transmission of location data may be adopted to balance monitoring requirements and battery life.

Which of the statements given above are correct?

(a) 1, 2 and 3 only
(b) 1, 3 and 4 only
(c) 2 and 4 only
(d) 1, 2, 3 and 4

Answer: (b) 

Explanation:

  • Statement 1 is Correct: GPS determines geographical position, but transmitting that information is a separate process.
  • Statement 2 is Incorrect: GPS enables positioning, whereas satellite communication transmits information.
  • Statement 3 is Correct: Terrain and vegetation can obstruct signal reception or satellite visibility.
  • Statement 4 is Correct: Transmission frequency involves balancing monitoring needs against battery life and collar durability.
